The 2020+ Ford F250/350 Platform is the same as the 17-19 but they lowered the front 1″ and the rear 1″-1.5″ depending on the cab configuration and 250/350 designation. For this reason, the only change to the suspension systems will be the stated lift height. The 2.5″ Lift Systems from the previous generation, 2017-19, are now 3.5″ for the 2020.
