Description

The Rough Country 6-Inch Lift Kit is meticulously engineered to transform your 2014-2018 Chevrolet Silverado or GMC Sierra 1500 4WD, delivering a bold, level, and aggressive stance. This kit is designed to eliminate factory rake and accommodate up to 33-inch tires on factory 20-inch wheels, allowing you to retain your OE styling while enhancing off-road presence. Constructed with strength and precision in mind, the kit features heavy-duty fabricated lift blocks that surpass cast alternatives in durability. The high-clearance crossmember design maximizes ground clearance for improved off-road capability and obstacle navigation. Suspension components are precision laser-cut using advanced CAD technology for a perfect, factory-style fit. Buyers can choose between nitrogen-charged N3 shocks or M1 Monotubes to customize their ride experience. Installation of this kit requires cutting and drilling. It is essential to confirm stock control arm material (cast aluminum, cast steel, or stamped steel) for proper fitment. Please note that this lift 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 due to additional drivetrain components and sensor placement. For models with a mass damper on the front differential, it must be removed to ensure adequate clearance when lowering the differential. Professional installation and a post-lift alignment are strongly recommended. If installing tires wider than 295/60R20, offset wheels may be required, and trimming might be necessary. A 0.25-inch wheel spacer is required to retain factory wheels. Installation of larger tires will also require Rough Country's Speedometer Calibrator SKU: 90009.
