The fourth-generation Sierra 1500 and Silverado 1500 from GM features an all-new design that’s built from the ground up, with aggressive angles and head-turning stylings that fit beautifully when transformed with Rough Country’s 4in Suspension Lift.
This kit levels and lifts your vehicle for a commanding stance and enough clearance to run 35x12.50 tires on 10in wide wheels.
Engineered by Rough Country, this kit retains optimal suspension geometry while keeping the factory ride quality, giving you off-road capabilities without sacrificing the handling and smooth ride that makes this truck impressive.
Rough Country’s 4in Suspension lift maintains the stock track width, allowing for up to a 10in wide wheel with 4.5in backspacing.
Each kit includes front and rear crossmembers and a skid plate for chassis strength as well as cast steel knuckles for durability and performance.
Includes Rough Country’s Lifetime Replacement Guarantee!
Fitment Notes: This kit fits only Chevy Trail Boss and GMC AT4 models and does not fit standard trims or other GMC models.
It is incompatible with GMC Denali models equipped with Magnetic Ride Control, AT4X or ZR2 models with Multimatic DSSV suspension, vehicles with composite leaf springs, two-piece rear driveshafts, 2019 “Classic” models (2018 body style), or 2025 models with multi-leaf springs.
Installation requires cutting and drilling.
Factory wheels will not fit—20" or larger aftermarket wheels with 4.5" backspacing are required.
Verify wheel compatibility with 2019-up GM large brake calipers, test-fitting is recommended, and some aftermarket wheels may need a 0.25" wheel spacer (SKU #1065).
