Description

The Rough Country 3.5 Inch Lift Kit offers an ideal balance of aggressive looks, increased ground clearance, and everyday drivability for Chevrolet Silverado and GMC Sierra 1500 models. This kit utilizes precision-engineered lifted knuckles that retain factory suspension components for a dependable and hassle-free installation. A key design feature is the repositioning of the CV axle, which enhances clearance from the lower control arm, significantly reducing boot fatigue and protecting your drivetrain from potential damage. This lift kit aims to eliminate the factory rake by providing a level front-to-rear stance, which not only improves aesthetics but also contributes to better vehicle balance and confident handling both on and off-road. For ride quality, it comes equipped with Rough Country's premium N3 shocks, featuring 10-stage variable valving and nitrogen charging for a blend of off-road capability and on-road comfort. The system is also fully configurable with other Rough Country shock and strut options, including the Vertex reservoir upgrade. This kit is designed for 2014-2018 Chevy Silverado 1500 4WD, 2019 GMC Sierra 1500 Limited 4WD, 2019 Chevy Silverado 1500 LD 4WD, and 2014-2018 GMC Sierra 1500 4WD models. It requires cutting and grinding for installation and does NOT work with aftermarket control arms. Notably, this kit does NOT fit Denali or Denali Ultimate models equipped with Magnetic Ride Control, nor does it fit models with the eAssist (ECO Hybrid) package. Users must confirm their stock control arm material (cast aluminum, cast steel, or stamped steel) to ensure proper fitment. Additionally, models equipped with a mass damper on the front differential must have it removed to ensure adequate clearance when lowering the differential. A 0.25-inch wheel spacer is required to retain factory wheels.
