Tremor Update: 09/11/2020
We’ve now measured a stock Tremor to “confirm” Lift heights. The Factory F350 Tremor and Non Tremor measure as follows:
Stock F350
Fender Lip to Floor
Left Front: 40 1/4
Right Front: 40 5/8
Left Rear: 43 1/4
Right Rear: 43 3/4
Bump Stop to Axle
Left Front: 2 7/8
Right Front: 3 1/8
Left Rear: 9
Right Rear: 9 7/8
Stock F350 Tremor
Fender lip to floor
Left Front: 41 1/4
Right Front: 41 5/8
Left Rear: 44 3/8
Right Rear: 44 3/4
Bump Stop to Axle
Left Front: 4 3/4
Right Front: 4 7/8
Left Rear: 10 3/8
Right Rear: 10 5/8
Measuring a stock Tremor against a standard Super duty shows the Tremor to sit approximately 1-7/8″ higher in the front. The rear has quite a bit more lean on the standard Super Duty but, if averaged, about 1″ taller in the rear.
With this in mind, our 3.5″ and 5.5″ systems on the standard Super Duty will actually be a 1.5″ and 3.5″ System on a Tremor.
2020 F350 Super Duty, 6.7L – R&D
Well, she looks a bit different and we’re happy to report the ONLY change is the stated lift height. Everything bolted on just as it had to the 2017-19 platform. There were concerns that the 10 speed transmission and updated transfer case brought a new front CV style front Driveshaft (at the transfer case) but all was well within operational range of motion through our whole travel stroke.
We touched on the fact that Ford lowered the Super Duty Platform in the earlier article (scroll to the bottom of this page). How much and why? As usual, there’s a variance. The F250 and F350 saw anywhere from a 1-1.5″ lower front spring and 1″-2″ lower rear. This varies based on cab and trim package and F250 vs. F350. Both trucks appear to have shrunk the rear block to a 2″ but the F250 has a 2-spring main leaf pack with a lower overload while the F350 comes with a 3-spring main pack with an upper and lower overload accounting for it’s slightly higher rear stance. Luckily, none of this impedes the installation of Carli Lift Systems – all that changes is the stated lift height.
The installation of our 4.5″ system went off without a hitch. The coils measured out to approximately 5.5″ of lift on this platform confirming, once again, that the height modification to the factory suspension was relegated to the springs/blocks, NOT the mounting provisions. The Radius Arm Drop Brackets bolted into place without issue as did the shocks and Radius Arms, Brake lines, Torsion Sway Bar, Adjustable Track Bar and High Mount steering Stabilizer.
Moving onto the rear was the same story. The stance was perfect as the lift provided to the 2020 resulted in the same measurements as those with the 4.5″ on a 2017-19. This truck is equipped with every option – the Full progressive Leaf Springs, Long Travel Airbags and King 2.5″ Remote Reservoir Shocks to match the fronts. Measuring the wheel wells, the rear sat 1/2″ taller than the front. Our measuring point is always the pinch weld as it’s flat, not skewed like the fender arches. From the pinch weld, we see a 3/8″ rear high stance – just enough to not appear front high as a perfectly leveled truck will.
17s have also been confirmed to fit the 2020s despite Ford’s recommendation for 18+. So long as the recommended wheel specifications are followed – 17×9 with 4.75″ – 5.0″ backspace – we appear to be in the clear! This customer is running Method NV in a 17×8.5″ (8x170mm) with a 0 offset, 4.75″ Backspace. No trimming was required to tuck the respectable 37×13.5″ Toyo MT Tires. These maintained an aggressive stance with minimal tire-poke and thus, little concern of rock-chucking at the fresh paint. A 5″ Backspace would fit with slightly less poke as would a 5.5″ (with Carli Radius arms) for the least amount of tire protrusion from the fender.
So what does all this mean? All that’s left to do is the administrative portion. We need to get these systems up on the website with the proper lift height data populated – customers can feel free to order systems in the interim understanding that their vehicles will achieve approximately 1″ more lift that stated when ordering a 2017-19 lift system. We’ll send out a notification once the 2020 section of the website has been populated. Here are more pictures of this truck for your viewing pleasure!

Thankfully, the 2020 is no far cry from it’s predecessor. An updated front end, MASSIVE diffuser and lower stance seem to be what separate it from its predecessor – well, as far as we’re concerned. There are many more changes (Interior, 10 Speed Trans, etc.) but this isn’t a vehicle review; this is an article in response to those calling in chomping at the bit for us release our system fitment information. In reviewing the stock 2020 platform, the suspension appears to have been lowered about 1″ all around comparing the measurements to the 2018 measured the week prior.
Here’s the issue – lowering a straight axle vehicle brings the frame and axle closer together. In short, you’re giving up travel on the “compression” end of the stroke. Think any bump that doesn’t have a dip before you encounter it – driveways, speed-bumps, etc. To account for this, you’ll notice there’s no more large, yellow, cushy foam bump stop to which super duty owners have become accustomed. In shrinking this gap, the bump stop changed from a large, supple stop to a black SOLID stop. Why? How much room are they working with? Glad you asked.
Yup, there’s 1″ of up-travel before you hit the factory bump stop. Actual up-travel (bump stop removed) is 2-7/8″. Total travel, 7″. Lets say you encounter a large front end hit and are able to compress the factory stop 1″ overall, you’re working with 6 total inches of suspension travel – about what we expected overall but FAR less up-travel which is most important in daily driving scenarios. The questions surrounding the new platform focused on whether we’d be making a 2.5″ lift for the 2020 guys specifically or putting our existing 2005-19: 2.5″ lift coils and stating a taller lift height as we were starting with a lower vehicle. Well, the answer is the latter. Why? Because a 2.5″ lift coil would still only net 3.5″ until you contact the bump stops. Designing Performance Suspension Systems, we err on the side of more travel whenever possible.
We installed the entire front Pintop 2.5 Base System:
- Carli 2.5″ lift coil springs
- Carli Spec King 2.5″ Remote Reservoir Shocks
- Adjustable Track Bar
- Extended Brake Lines
- High Clearance Front Bump Stop Cups
- Torsion Sway bar
Everything Bolted in with ease! So let’s talk measurements. We take SEVERAL measurements in the R&D department, many of them redundant to confirm heights at multiple points of the vehicle. The two with which we’ll focus here:
- Fender to floor: We keep the wheels and tires (including pressure) the same. This is great to measure before and after lift but isn’t a good reference point for an end-user as it varies with tire height & body mount condition (not relevant on a new truck).
- Bump Stop Strike Plate to Frame: This is the best measurement to use to isolate the suspension measurement. There are no other variables here.

Analysis of the above numbers indicates the the rear of this STOCK 2020 F350 to be about 3″ Taller than the front according to the fender measurements. Another interesting thing to note, the Super Duty lean continues! At the fender, we’re seeing 3/8″ difference, 1/2″ in the rear (lower on the driver’s side). The bump stop to axle measurements confirm the lean but don’t do much aside from setup a baseline for the after measurements.
Of course, we recommend a rear spring modification with ALL Carli Systems. Nothing we sell in the Super Duty Suspension System lineup is optimized for the factory spring pack with no Progressive Add-a-pack or Full Progressive Leaf Spring pack. That said, many people have purchased our “Base Kits” without the rear spring option so we thought it to be worth mentioning that this truck sat dead-nuts with our front spring.
Isolating the suspension using the Bump Stop to axle measurement; this truck received 3.5″ of lift from our 2.5″ coil springs confirming that these trucks were lowered 1″ via a shorter coil spring by Ford. With the Rear King Shocks installed and charged with nitrogen (the only modification to the rear), the rear end actually came up slightly. Well, raising the front of the truck may have slightly unloaded the rear springs causing the lift as well. Regardless of the cause, the truck sits PERFECTLY level at the fender perspective. This is with the factory leaf spring with the 2-1/8″ tall F350 block installed. The F250 will be a different story as it has fewer leaf springs in it’s main pack. It will likely require a taller block or spring modification to sit level with our front springs installed.
Next week, we get into the rear options. Add-a-Pack configuration for this truck will be figured out, full spring install will happen, then we’re throwing it up to a 4.5″ Pintop System with every option! We should be done with ALL options within the next couple weeks. Following this truck, Tremors and Gas (7.3L) are scheduled. Stay tuned….

I have a 2022 f350 long bed and was originally going to go with a Fabtech 8″ kit but I realized 8″ was just a little too big. I still want the “lifted truck” look in comparisons to the “leveled truck” look. being that its a 2022 if I go with the 5.5 pinto kit, will I lose the 1″ so it is actually a 4.5″?
Hi Trevor – Your truck will get 5.5″ of lift from the kit as it’s a 2020-22 model.
Morning, I have a 2022 F350 KR Tremor completely stock, I would like to level it at first and if the jump in price to a full lift kit. what would be required to level the truck?
Hey Hunter – The mininum needed to level the Tremor can be found HERE. This will bring the front of the truck up 1.5″ over stock form; the rear will still be about 1″ taller than the front; perfect for a truck that still gets used.
I have a 2021 F-250 Super Duty 6.7L. Will it sit level with the 3.5” kit by itself or do I need to add something to the rear along with the 3.5” kit to make it sit level?
Hi Gordon – The leveling kit description outlines the following:
This system will not achieve a proper rear high stance without the installation of the add-a-pack and the matching rear shocks; it will sit slightly rear low with no rear option added! One can install the 3″ factory rear block for a leveled stance but rear ride quality will not be optimized (Factory Block PN: HC3Z-5598-A and HC3Z-5598-B). The Add-a-Pack installs in place of the lower, factory overload spring effectively making the factory leaf spring pack progressive in nature. In the 2020 platform, the factory 2″ block is eliminated with the installation of the Add-a-Pack; thus, axle wrap and wheel hop are non-existent.
Thanks, Dan. If I went with the Full Progressive Leaf Springs instead of the Add-A-Packs, would that still achieve the proper leveled stance?
If I do not want to Level my new 2022 f-350. If I want to keep the same rake, and if I want to install the Carli suspension for all its other Benefits, I’d there an option for me?
There is not, unfortunately. The 1″ of suspension travel you have before you hit the bump stops on your frame is not conducive to softening the suspension; a lift is necessary to do so!
With the way this truck is setup and the wheel and tire package that is on it do the tires clear (no rubbing) when steering is at full lock (left or right) while the suspension is compressed? I understand they clear on flat ground but what about on rough terrain?
37’s on 0 offset wheels are the best bet if you’re looking to clear while running off-road.
Okay, so after reading all this (and thank you so much for putting all this info out there for us!) I conclude that, on a F350 anyway, a 2.5″ spacer type level kit will only add the 2.5″ because you are not replacing the new shorter Ford coils. That means, according to your measurements, that if I install a 2.5″ spacer type level kit (and don’t touch the rear) then my front end will be .5″ shorter than my rear end? The thing is, after looking at a ton of pictures from guys doing the 2.5″ spacer level, some of them look nose high. I’m thinking about going with a 2″ spacer kit to achieve more noticeable rake to avoid the nose high look. And I’m still going to try and squeeze 37X12.50s on the stock wheel on that sucker!
One more question, and I realize this is not your product, but do you think using the relocation hardware (track bar relocation bracket, shock extender brackets etc) for a 2.5″ spacer kit but replacing the spacer with a 2″ puck instead would be a problem? It seems like going only .5″ shorter would still be okay with all that stuff?
AND, yes, it is Christmas Eve….so, MERRY CHRISTMAS (I fully expect to get a response next week, if I get one at all considering I’m not asking about your particular products and just general lift/level geometry instead. But, hey, you guys at Carli are the experts in this field!)
Hey Ray – We wouldn’t advise on this… Spacers aren’t our gig, 37s on stock wheels is another big no-no and relocating a track bar on a 2″ lift isn’t the way we’d go about it. All in all, there’s a reason we’ve engineered our systems to include what they do, every part has a purpose. I could get into detail on why each of the components about which you’re inquiring would cause an issue but that would be a phone conversation vs. getting into all that on here. There’s the cheap way, then there’s the right way!
My order was placed this morning for a Tremor with the 7.3. Your Pintop system sounds like my best option but is there a “Dominator System” in R&D yet for the 7.3?
Hi Chris, There is no dominator for the 2017+ Super Duty at this time.
Hi – just ordered a 2021 F250 Super Duty. Planning on using your products and I’m not that far away from your shop. If you need a 2021 to prove the kit out on let me know. Fleet manager said the truck should (estimate) in Jan 2021 some time. Ford switches over products mid November to the 2021 model.
How much will the Full Progressive Leaf Spring raise the rear of the truck on a 2.5/3.5 pinto level package? I see in the write up that without it is 3/8″ with stock leafs, but I don’t see anywhere that tells what happens when you replace with Progressive?
Hey Earl, the rear Full Progressive Leaf springs raise the rear around 2″.
Looking at getting a back country kit but not looking to get the add a pack in the rear. Will this sit level until I decide to pull the trigger and will your kit handle Canada’s winter climate -30/-45 Celsius ?
How much additional lift would the 2.5” pintop be on a tremor since they already come with a 2” front lift from the factory? Would the front be just be 0.5” taller than stock with the pintop 2.5?
I have a 2013 f250 XL work truck with the 6.2 L gas. I just ordered a Pintop 2.5 system to smooth out the harsh and jarring ride of the truck. With the diesel specific kit with its stiffer springs and shocks, would it make the truck ride smooth?
Hi Dylan, please see this article for the Gas specific systems: https://www.carlisuspension.com/super-duty-gas/
I was reading that you mentioned the “Ford lean”. Is that typical for the Super Duty. My friend put on a 4″ lift on his 2020 F250 ( I wont mention the company), but after it was done it was leaning on the drive side almost an inch and half different. The company said its a Ford issue and not there product. Is that true; it is a Ford issue? Will that happen with your product? Looking at his truck makes me a little weary about lifting mine.
Hi Doug, The Super Duty Lean was really only problematic 2005-16. There’s a slight lean to the Driver’s side on the new trucks – nowhere near as bad as the old trucks and our 4.5″ coils are taller on the driver’s side by about 1/4″ to compensate for this.
I tried reading but could not find the information (sure I just overlooked)
On the 2020 what rear block are you using with air suspension? It doesn’t look to have bump arm which is a problem with air lift
Hi Jay, We’re not. The 2.5″ lifts will require you to use a lower bracket that connects to the axle (usually a 2wd variant as they don’t come from the factory with a block) and a daystar cradle – your retailer should be able to assist you with this configuration. Our bags to match the 4.5″ connect directly to the axle so it’s not a concern.
Any word on the 2020 7.3 gas systems yet, to fit a Tremor 7.3 in particular? Patiently waiting.
Hi Ed, The gas kits have all been approved and are waiting on production! Should see them shipping late 2020.
will you have a 5 1/2 in kit for the 7.3 gas ?
Hi David, no plans at the moment – just the 2.5-3″
Great news! I just bought a 2020 F250 Tremor with the 7.3L and I’m gonna throw on your pintop King setup as soon as it’s available. Will all the options that can be had with the diesel kits be also available at the same time or is further R&D time needed? Ie leaf kits, radius arms, sway bars etc?
Hey Sam, All options on the diesel are applicable to the gas!
Is there recommended alignment specs for 3.5” on my 2020 F250? I have the full pin top with the progressive leaf springs. The ride is not great at all and I am trying to find out if there anything I need to check. The truck will jar your teeth out right now if you hit a man hole cover.
Hi Brandon – I have forwarded your email to Tyler. He should be reaching out shortly to assist you in trouble-shooting your Pintop System as it should be riding far better than you describe.
Looking for levelling kit for 2020 F250 Tremor 6.7 diesel. Looking to run 37’s on the stock 18 rims.
Any time frame for such a kit?
Already available! Give one of our retailers a call!
I have a 2020 F-250 superduty 6.7.
Looking to level my truck with back county package.. I want to use stock wheels and toyo opencounty 295’s. Will this product dramatically improve my ride quality? I’m looking for performance. Drives me crazy driving on backroads or on the ranch. What will I need on front end and rear end to achieve level and performance? Without all the extra?
Hey Thomas, yes, there’s a significant improvement to be had. Back-road driving will be optimized with the addition of the Torsion Sway Bar and Full progressive Leaf Springs. None of our systems are “optimized” to run with the super-limiting stock rear leaf springs. The add-a-packs will be a great addition, the full springs will take it to the next level!
I have a 2020 F250 7.3L with the Tremor package. Will there be a kit available in the next 6-8 weeks? I am looking at the 2.5” back country kit with the sway bar add. What would be the biggest tire I could install if I keep the stock arms. Same question if I have Carli’s arms installed. I am having CJC Off road do the install and they are 6-8 weeks out. So if you have a specific kit coming out for the 7.3L I’ll hold off on the install. Thanks.
Hi Mike, We’re probably 4-6 months out on the 7.3L kits at the moment!
Thanks for the information.
Hi Dan,
Any updates on the leveling kit for the 2020 F250 7.3L Gas? Thanks.
Hi Mike, Everything is signed off – we’re awaiting our custom prints from Fox, then we order. Hoping this is all done within the month resulting in a 3-4 month lead time if all goes well!
Thanks for the update. I have your 2.5 leveling kit on my 2020 F250 with the 7.3L gas. Is there a big difference between the springs and shocks I have now versus the new kit for the 7.3? Just trying to see if the difference is worth switching my springs and shocks out when the new kit is released. Any info would help. Thanks.
Forgot my kit now is the 2.5 leveling back country kit.
Yes, the spring rates are substantially lower on the gas truck and the valving is very different as well!
On a 2020 250, to be level at the fender when installing the base kit on a 7.3L Gas, you would need to replace the stock 2 inch block with a 3 inch block, not the 2020 350 block, as they same now right? Assuming the same front end lift the old 6.2L has got, and no Add-a-pack springs?
Hi Jonathan, We don’t have a gas-specific kit but have had several customers install our diesel kits with success. We recommend an extra inch of lift in the rear to compensate for the additional lift the Diesel springs provide the gas motor. A popular choice is the Commuter 2.0 System with rear add-a-packs. This will provide a 3-3.5″ front lift.
We have prototype gas coil springs that have been tested on the 11-16 6.2L Gas truck that sat at exactly 2.5″ of lift – next, we’re going to put them on the 2020+ 7.3L to confirm fitment on that truck before green-lighting the springs. This is all currently in process and we’ll likely see it come to fruition middle to late 2020.
I hope all is well with the Carli team and everyone is healthy and safe. Has the current conditions effected anticipated delivery of your suspension kits? If I recall there was a 4 week wait on Fox shocks for the 2020 Ford Commuter kits.
Hi Rob, All is well over here at the moment but things are getting crazier by the day! Yes, everything is being delayed as our vendors shut down amidst the chaos. If you have a particular kit for which you’d like to check ETA, contact your local, stocking retailer. Stay safe out there!
I have a 2020 Tremor with the 7.3 gas motor. Do you have a time frame as to when the leveling coils (caster shims, bump stops etc.) may be available for the Tremor/7.3 gas package?
Hi Ed, we have a proto truck lined up for the gas R&D, with the current COVID-19 concerns – we’re hesitant to have the customer ship it in. As information becomes available and things stabilize, we’ll move forward with R&D.
Is it also certain that the track bar brackets and pitman arms between the 17-19 and 20s are the same? These were the only items I did not see directly addressed. Also are there any plans to improve at least the front reservoir mounts? Standard hose clamps and an $80k+ MSRP truck just don’t seem to go together. The rears aren’t as big of a deal because they are hidden but a nice wheel well mount would be a great added appeal factor.
We’ve talked about it but the Stainless hose clamps do the job well and the complaints are rare. Some heat-shrink them to “clean” up the look, others spring for billet clamps that are bulky – the function of a simple hose clamp is hard to argue!
I’m waiting for a leveling kit for the 2020 F250 Tremor 6.7L. Hope you guys get to working on this soon!
Word is that the coils will work perfect to level the tremor. Still waiting to get one in to measure!
I have a 2020 F250 with the heavy duty tow. Does it already have the rear blocking as a 350 would? If I add the 2.5 lift in the front would it sit level?
Hi Dave, it’s not an F350 block – they both (F250 & 350) come with the same 2″ rear block. The F350 comes with 3 main springs in the leaf pack with a lower overload (1″ spring that doesn’t follow the contour of the pack). Does yours have 2 or 3 main leaf springs?
The 2020 F250 with heavy duty tow package I installed Carli full rear springs on had the 2″ block with 3 main springs and an upper and lower overload which sounds like the exact same as the F350. I know the F250 with heavy duty tow shares the same rear end as the F350 SRW which is different than the standard F250 rear end. (this also is the only way to get 3.55 gears in a F250).
Great information!
I have a 2020 F250 with 7.3. If going with the 2.5 will you guys have a rear block to replace the stock one to keep my truck level or would I need to source a stock F350 rear block?
Hi Tim, We don’t have a gas-specific kit but have had several customers install our diesel kits with success. We recommend an extra inch of lift in the rear to compensate for the additional lift the Diesel springs provide the gas motor. A popular choice is the Commuter 2.0 System with rear add-a-packs. We have prototype gas coil springs that have been tested on the 11-16 6.2L Gas truck that sat at exactly 2.5″ of lift – next, we’re going to put them on the 2020+ 7.3L to confirm fitment on that truck before green-lighting the springs. This is all currently in process and we’ll likely see it come to fruition middle to late 2020. All this being said, we’re likely going to provide the PN for customers to source the Factory F350 Block vs. providing a block. Nothing is yet set in stone.
Thanks for the reply! I’ve ordered a kit and having it installed today. I did get some taller factory blocks from the dealer. We’ll see how it turns out. Hoping for the best
Let us know how it works out!
I have a 2020 with the tremor pkg and I’m looking to upgrade the track bar but I don’t want to lift the truck any. Will your track bar adjust for stock height or do you have something in the works?
Hi Rich, We won’t be doing an adjustable track bar for stock height Super Duties, sorry!
Whaaaat we got it in writing now?! I absolutely can not wait for the 4.5 pin top, and then dominator WHEN y’all get it figured out. Waiting to order a 7.3 gasser because the only reason to get a new truck is so I can put a carli kit on it. I’ll keep checking in. Feel free to email updates.
Thanks, Ryan! Sign up for our newsletter and you’ll be the first to hear about product releases!
I had a 2017 F350 long bed that had a 2.5 ready lift level…It seemed like it had just a little bit of rake. Very slight.
Now I have a 2017 F350 long bed and am debating between the 2.5 and the 4.5. Do you have any pictures to illustrate the difference. Also, how will I need to handle the rear? I want rake regardless of what I do. From what I have read, it seems like the add a pack works for both the 2.5 and 4.5? Or do you need an additional block to lift it up to work with the 4.5?
correction. Now I have a 2020 F350 long bed
Hi Bryce, the Add-a-pack works with no block for a 1/2″ rear high stance on the 2.5″ and in conjunction with our 2″ block to provide the same 1/2″ high stance on the 4.5″.
I have a 2020 f350 srw
How will your 2.5 springs hold up to handling a boss 9.2 v blade
Depends on the weight of the plow. I looked it up but BOSS doesn’t porvide the weight in an easily sourced document. Our coils are shot peened, pre-set (pre-fatigued, when you receive them, they’re sagged to the lowest point they’ll go) and powder coated by the manufacturer to ensure the longest lasting set of springs on the market. That said, they’re a lightened spring rate than the factory coils BUT they sit higher. With the plow installed, our springs will drop to around factory height and will handle the approx. 1,000lbs; when the plow is dropped, they’ll bounce right back up to their stated 2.5″ height. No springs on the front of a non-commercial vehicle “like” the load of a plow but they’ll tolerate it better than any other aftermarket spring.
I have a 2020 F-350 Dually and it has no rear block at all on the rear (spring is setting on the rear axle housing) will you be coming out with a kit for the duallys also?
We plan to address the trucks with no blocks as well, yes!
