4 Inch Lift Kit | Diesel | Chevy/GMC 1500 2WD/4WD (25-26)

Explore new heights
Transform your truck with Rough Country'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 Rough Country'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 Rough Country 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.

We didn't want to limit you to one standard kit. Rough Country's 4-inch kit is configurable with all the shock options that we offer. This allows you to choose which shock series you want! Ranging from our nitrogen-charged N3 shocks to our Vertex reservoir shocks the power to choose is in your hands.

Installation
With minor cutting and a strut compressor required to install, an estimated timeframe of 8-10 hours is recommended to complete this full installation. This full kit can be installed at home and can be completed efficiently and quickly!

Limited lifetime replacement warranty
Rough Country's 4" suspension lift kit is backed with a limited lifetime replacement warranty towards manufacturer defects. As such, the product is protected from structural and workmanship damage after the date of purchase. With our industry-leading warranty give yourself peace of mind when using Rough Country's suspension products!
