Rough Country 21731D 6" Lift Kit With N3 Shocks

The Rough Country 21731D 6" Lift Kit With N3 Shocks from XDP is a great option for anyone looking to change the look of their Chevrolet Silverado 1500 3.0L Duramax 2WD/4WD. Chevy's fourth generation 1500 features an impressive design that's built from the ground up, with aggressive angles and head-turning styling that fit in beautifully when transformed with Rough Country's 6-inch Suspension Lift.

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. This suspension kit combines the use of durable steel knuckles, differential brackets, and drop cross members to reduce CV angles and simulate factory angles all while achieving new heights. Featuring a set of upper strut spacers that offer uncompromised strength and rigidity, gaining lift height is no issue. Completing the rear of this suspension kit is a set of rear blocks, shocks, and U-bolts that allow you to retain factory-like geometry. This combined setup provides enough clearance to run 35" tires without additional modifications.
