About this kit
2.5-Inch Lift Kit with M1 Struts, fitment-checked
Rough Country 510040 is a 2.5-inch lift kit for the 2021-2025 Ford F-150 Tremor 4WD. It pairs M1 loaded struts up front with a 1 inch block and U-bolt kit out back, raising the front 2.5 in while bringing the rear down 1.25 in for a level stance. Tremor models only — it does not fit other F-150 configurations.
This 2.5 inch lift kit for the 2021-2025 Ford F-150 Tremor 4WD ships as two assemblies: an M1 loaded strut pair for the front and a 1 inch block and U-bolt kit for the rear. The result is 2.5 in of front height with the rear settled 1.25 in, evening out the factory rake. Per Rough Country, the resulting clearance accepts a 35 x 12.5 tire on the OE wheels with no trimming. Confirm your truck is a Tremor before ordering, and review the downloadable Rough Country installation guide first.
