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.
This is the reason for the 4.5″ and 5.5″ lift designations within the shock packages; this is not a lift range but references the proper lift height relative to the model year. 4.5″ lifts on the 2017-19 and 5.5″ lifts on the 2020+ utilize the same shock packages.
