Give your fifth-generation Ford F250 and F350 Super Duty a major boost in performance, capability, and stance with Rough Country’s 6-Inch Radius Arm Drop Suspension Lift. Designed to maintain factory ride quality while accommodating up to 37-inch tires, this system provides a comprehensive suspension transformation that does not compromise comfort or drivability.
The key to preserving a smooth ride after lifting is maintaining proper suspension geometry, and this kit delivers exactly that. Heavy-duty tubular radius arms—built with a massive 2" outer diameter—bolt directly into the factory mounts, restoring angles closer to stock for improved ride characteristics. Durable rubber bushings help absorb vibrations, offering a more controlled and comfortable driving experience both on and off the road.
This lift also includes application-valved N3 Nitro Gas Shocks, M1 Monotube Gas Shocks or V2 Monotube Gas Shocks
