    Rough Country 51240 Features:

    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. This kit includes a set of lifted coil springs and ultra-durable, fabricated anti-wrap rear blocks that prevent binding and axle wrap.
