Rough Country's 6-inch Radius Arm Drop Suspension Lift gives your 2023-2026 F-250 or F-350 Super Duty 4WD the clearance to run up to 37-inch tires while keeping suspension geometry close enough to factory angles that everyday drivability stays intact. Radius arm drop brackets bolt directly to the factory mounts, preserving proper caster and eliminating the handling compromise that plagues poorly engineered lift kits. Every component in this all-inclusive kit ships ready to install, so there is no sourcing separate hardware or adapters.
Geometry-correct radius arm drop brackets. Caster angle determines how your Super Duty tracks and returns to center after turns. Rough Country's radius arm drop brackets reposition the front axle relative to the frame at the correct caster angle, so steering feel, tire wear, and highway stability remain predictable at 6 inches of lift.
Application-valved N3 shock absorbers. Each shock in this kit is valved specifically for the Super Duty platform, balancing compression and rebound for both pavement and trail use. Swapping in generic shocks at lift height causes a harsh, unpredictable ride; the N3 units included here are tuned to work with the added travel this kit creates.
Fabricated rear lift blocks with anti-axle-wrap design. Fabricated steel blocks outlast cast alternatives and resist cracking under heavy load cycles. Rough Country's anti-axle-wrap geometry distributes forces across the block during hard acceleration, eliminating the wheel hop and block rotation common with standard lift blocks.
Installation requires cutting and drilling. Plan for 6 to 10 hours in the shop. The kit can be completed at home with proper tools, and all components are engineered to fit the factory mounts for a straightforward, well-documented process.
