Take your truck to new heights with Rough Country's 6in Radius Arm Suspension Lift! This all-inclusive kit comes with everything you need for a total trasnformation of your truck. Run up to 37in tires while preserving the smooth, factory ride quality with this impressive upgrade.

When changing a vehicle's suspension, the key to preserving ride quality is keeping the geometry of all suspension components as close to their factory angles as possible. Rough Country's new 6-inch Radius Arm Suspension Lift features a set of ultra-durable Radius Arms, precision fit to bolt right into the factory mounts for an easier install and a more factory-like angle. At 27lbs each, these beefy, upgraded Radius Arms dwarf stock equipment and feature durable Clevite Rubber Bushings for maximum vibration absorption.

 


Local pickup welcome.

Some vehicles may require additional modifications or parts.

Guaranteed Fitment.
