About this kit
6-Inch Diesel Lift Kit, fitment-checked
Part 21731D is the diesel-oriented take on Rough Country's 6-inch Silverado 1500 lift: alongside the standard 6-inch front kit box it carries a diesel-specific front kit box, cast knuckle boxes, and a high-clearance crossmember. Coverage runs 2019–2024 in 4WD, plus the 2022 Silverado 1500 LTD.
Order this 6-inch lift kit for a 2019–2024 Chevy Silverado 1500 4WD and the difference from the standard version is up front: a dedicated diesel front kit box ships alongside the regular 6-inch front components. Everything else follows the platform — driver and passenger cast knuckle boxes, a high-clearance crossmember, and a universal kit box. Trail Boss, ZR2, and Adaptive Ride Control trucks are excluded, as are 2019 Classic body-style trucks. Cutting and drilling are required, and a downloadable installation guide is available. Shipping weight: 223 lb.
