Built for GMC Sierra Denali 1500 owners who want an aggressive lifted stance with factory ride quality, this 6-inch lift kit delivers a level platform for bigger rubber without sacrificing driveability. Rough Country's lifted-knuckle design keeps suspension geometry optimized, and you'll run up to 33-inch tires on your factory 20-inch wheels.

What's included
- Steel Control Arm Knuckle — Beefy lifted design that boosts ride height while maintaining optimum suspension angles for a factory-like ride.
- Front and rear high-clearance crossmembers — Laser-cut precision components with RC branding and integrated differential skid-plate for maximum ground clearance.
- Fabricated lift blocks — Stronger and longer-lasting than cast alternatives, engineered for durability under lifted load.
- Complete kit box — All structural and fastening components needed for front and rear installation.
Important notes
- Installation requires cutting and drilling of frame components.
- ONLY fits GMC Denali models with factory Magnetic Ride Control. This kit is not compatible with standard Sierra 1500 or non-Denali variants.
- ONLY fits trucks with factory cast steel knuckles or control arms. Check your OE suspension before ordering.
- 18-inch or larger wheels are required.
- 33-inch tires fit on factory 20-inch wheels; for wider tires (over 33x12.50), offset wheels will be required and trimming may be necessary.
- If your truck is equipped with a mass damper on the front differential, it must be removed during installation.
- See installation instructions for complete tire and wheel combination guidance.
