Description

This Rough Country 6-inch suspension lift kit is engineered to elevate your 2019-2024 Chevy Silverado 1500 2WD/4WD, providing an aggressive stance and enhanced off-road capability. The innovative design utilizes durable steel knuckles, differential brackets, and drop cross members to preserve factory suspension angles and maintain ride quality. Upper strut spacers contribute to the lift height, while rear blocks, shocks, and U-bolts ensure factory-like geometry in the back. This setup allows for the fitment of up to 35-inch tires without additional modifications, and the kit is fully configurable with Rough Country's N3 or Vertex reservoir shock options for customized ride quality. Installation requires minor cutting and drilling, with an estimated timeframe of 8-10 hours. The kit comes with a Limited Lifetime Replacement Warranty. Important Fitment Notes: This lift kit requires cutting and drilling for installation. It does NOT fit 2019 "Classic" models (2018 body style). It is incompatible with models featuring Adaptive Ride Control. LT Trail Boss, Custom Trail Boss, and ZR2 models are excluded due to their factory lift and suspension components. Factory wheels will not fit; 20-inch or larger aftermarket wheels with 4.5-inch backspacing are required. Some aftermarket wheels may necessitate a 0.25-inch wheel spacer.
