Running larger tires on a fifth-generation Super Duty without wrecking the ride quality takes more than a simple spacer lift. Rough Country's 6-inch Radius Arm Lift Kit rebuilds the front geometry from the ground up, keeping suspension angles close to factory spec so your 2023-2026 F-250 or F-350 4WD drives like a truck, not a punishment. Cutting and drilling are required, but the end result is a fully transformed Super Duty capable of fitting up to 37-inch tires with confidence on and off the pavement.
Tubular radius arms that outclass stock. The kit replaces the factory radius arms with tubular steel units featuring a 2-inch outer diameter. These bolt directly into the factory mounting locations, preserving correct caster angle so steering feel and highway stability stay intact. Rubber bushings absorb vibration across the full range of driving conditions, from washboard dirt roads to daily highway commutes.
Application-valved premium shock absorbers. Each kit ships with shocks that are valved specifically for this lift height and the weight of the Super Duty platform. Buyers can select N3, M1 monotube, or V2 monotube shock options depending on their intended use, from daily driving to more aggressive off-road work. The shocks balance on-road comfort with off-road capability rather than forcing a compromise between the two.
Fabricated rear lift blocks with anti-axle-wrap design. The rear blocks are fabricated steel, which holds up longer under load than cast alternatives. A dedicated anti-axle-wrap geometry built into the block design maintains stock rear ride quality and eliminates the wheel hop and axle twist that plague conventional lift block setups under hard acceleration.
Limited lifetime replacement warranty. Rough Country backs this kit against structural and workmanship defects for the life of the product, covering the hardware from the date of purchase onward.
