The Rough Country Coilover conversion lift kits in brief

A coilover conversion swaps the front suspension for coilovers, and Rough Country offers it for the 2023-2026 Ford F-250 and F-350 Super Duty in three part numbers. Part number 43658 gives 3 in of front lift for the F-250 4WD. Part number 400158 gives 4.5 in and 400258 gives 6 in, both for diesel trucks. All three are 4WD only, all include shocks, and the maker recommends a professional alignment after installation. The kits use Vertex coilovers, radius arm drop brackets, anti-wrap rear lift blocks and two rear V2 shocks. The maker lists rear parts but states no rear lift height, so none is given here. The maker's own install estimate is 6-10 hours for each kit. The maker also lists radius-arm versions 400358 and 400458, though their details are not given here.

Which part number is yours

The three numbers split by lift height and truck. Part number 43658 (alternate 43657) is for the F-250 only; the maker says it does not fit the F-350 or a dually. Trucks with a 2-piece rear driveshaft need carrier-bearing drop bracket SKU 1197, and a factory top-mount overload spring must be removed. The maker's product name says 23-25 while its fitment list says 2023-2026, so confirm your model year. Part number 400158 (Vertex 400159) is 4.5 in and 400258 (Vertex 400259) is 6 in. Both are diesel only, include a carrier bearing drop bracket, and carry the maker's warning that ADAS and LiDAR recalibration may be necessary. Neither fits the Tremor Off-Road Package or a dually. Match three things on the listing before you buy: the lift height in the title, the part number, and whether your truck is a diesel F-250 or F-350 without the Tremor package.
