About this kit

6-Inch Lift Kit with N3 Shocks, fitment-checked

Rough Country 21631 is a 6-inch lift kit for compatible 2022–2024 Chevy Silverado 1500 4WD trucks, built around a mono-leaf rear setup, a high-clearance crossmember, cast steering knuckles, an N3 shock pair, and a loaded strut pair. Factory wheels will not clear it: plan on 20-inch or larger aftermarket wheels with 4.5in backspacing, and test fit before the install.

This 6-inch lift kit for the 2022–2024 Chevy Silverado 1500 4WD ships as a multi-box package: mono-leaf rear components, a 6in crossmember box, a front full skid, driver- and passenger-side knuckle boxes, an N3 shock pair, and a loaded strut pair. Installation calls for cutting and drilling. It does not fit 2019 "Classic" body-style trucks, models with Adaptive Ride Control, LT or Custom Trail Boss, or ZR2. Wheels must be 20-inch or larger aftermarket with 4.5in backspacing; some may need a 0.25" spacer, part #1065. A downloadable Rough Country installation guide is available.
