About this kit
6-Inch Lift Kit, fitment-checked
A 6-inch lift kit covering 2019–2024 Chevy Silverado 1500 4WD trucks plus the 2022 Silverado 1500 LTD. The box list runs to cast knuckle boxes, a high-clearance crossmember, a front full skid plate, and the 6-inch front lift components. Aftermarket wheels are mandatory — 20 inches or larger with 4.5in backspacing.
This 6-inch lift kit for the 2019–2024 Chevy Silverado 1500 4WD spans Custom through High Country, along with PPV and SSV fleet trucks and the 2022 Silverado 1500 LTD. Rough Country builds the lift around heavy-duty cast knuckles and a high-clearance crossmember, and the shock and strut package is configurable rather than fixed. Confirm your truck does not have Adaptive Ride Control, and note that Trail Boss and ZR2 trucks are excluded. Installation requires cutting and drilling; a downloadable installation guide is available. Shipping weight: 235 lb.
