Built for Chevy and GMC 1500 owners who want a level stance with serious off-road presence — this 6-inch lift kit eliminates factory rake and delivers a bold, aggressive appearance while supporting 35–37 inch tires.

Important notes

• Installation requires cutting and drilling. Confirm whether your stock control arms are cast aluminum, cast steel, or stamped steel before ordering — contact us if you need help identifying yours.
• Does NOT fit Denali or Denali Ultimate models equipped with Magnetic Ride Control.
• Does NOT fit models with the eAssist (ECO Hybrid) package due to additional drivetrain components and sensor placement.
• Models equipped with a front differential mass damper must have it removed to ensure adequate clearance when lowering the differential.
• Installation of 35–37 inch tires requires Rough Country's Speedometer Calibrator (SKU 90009) to maintain accurate speedometer function.
• Tires wider than 295/60R20 require offset wheels; trimming may be necessary. Test fit wheels prior to installation.
• To retain factory 20-inch wheels, a 0.25" wheel spacer (SKU 1065) is required.
