Description
Raise your Chevy Silverado 1500 or GMC Sierra 1500 4WD with confidence using the Tuff Country 16959KN 6" Lift Kit. This kit is designed for serious off-road capability while preserving a comfortable, factory-like ride, and it includes all the essential components for a straightforward bolt-on installation.
- Front/Rear Lift: 6" front lift and 4" rear lift for a balanced, aggressive stance that fits large tires without compromising handling.
- New steering knuckles: Eliminates the need to drop upper control arms, simplifying alignment and installation while maintaining steering geometry.
- Multi-piece sub-frame: A three-piece design that eases installation and improves drivetrain alignment during the lift process.
- Includes lateral compression arms: Enhances axle articulation and stability across challenging terrain.
- Tire compatibility: Supports up to 36" x 12.50" tires for a bold, capable off-road look and off-road traction.
- Shocks included: Four SX8000 shocks are included to deliver improved dampening and ride quality with the lifted setup.
- Complete hardware set: Cross members, skid plate, brake line relocation kit, differential drop brackets, torsion bar drop brackets, axle spacers, U-bolts, and add-a-leaf assemblies for a full, plug-and-play install.
- Durable construction: Black powder-coated components designed for long-lasting durability under harsh off-road conditions.
- Made in the USA and backed by a limited lifetime warranty for lasting peace of mind.
- Factory-ride feel, off-road durability: Engineered to replicate the smooth highway ride while delivering rugged off-road performance when you need it.
- Easy bolt-on installation: Designed to be installed with common shop tools, minimizing downtime and complexity.
- Shocks and compatibility note: Factory-length shocks must be replaced with extended shocks to install this lift properly; if you haven’t already, select extended SX8000 shocks in the options.
