Built for GMC Sierra 1500 Denali owners who want an aggressive lifted stance with factory-like ride quality, this 7-inch lift kit from Rough Country delivers increased ground clearance and level positioning while maintaining driveline geometry. The innovative lifted knuckle design keeps suspension components at optimum angles, so your truck rides as smooth as stock — just taller. You'll gain the ability to run 35-inch to 40-inch tires depending on wheel selection and trimming.

Important notes
- Magnetic Ride Control required: This kit is engineered only for GMC Sierra 1500 Denali models equipped with factory Magnetic Ride Control. Non-Denali and non-MRC variants are not compatible.
- Steel knuckles and control arms only: Truck must retain factory steel knuckles and control arms — aluminum variants are not supported.
- Wheel and tire requirements: Factory 20-inch wheels are compatible; 18-inch minimum wheel diameter required. Tires wider than 35×12.50 require offset wheels and may require trimming.
- Mass damper removal: If equipped with a front differential mass damper, it must be removed during installation.
- Installation labor: Kit requires cutting and drilling; professional installation is mandatory.
