Explore New Heights: Transform your truck with 's 4-inch Suspension Lift, perfectly designed to enhance the bold, aggressive styling of GM's all-new fourth-generation Sierra 1500 AT4 and Silverado 1500 Trailboss. These models, already equipped with GM's factory two-inch kit, are taken to the next level with 's lift kit—giving your vehicle a commanding presence on and off the road.

Whether you're tackling tough trails or cruising through city streets, the 4-inch Lift ensures improved performance and head-turning appeal.Innovative Design and Construction: 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.
