Tuff Country 16993 6" Lift Kit with Knuckles and 3 Piece Sub-Frame No Shocks
Product Details
Description
Upgrade your Chevy Silverado 2500HD or GMC Sierra 2500HD 4WD with the Tuff Country 16993 6" lift kit. This bolt-on system is designed for torsion-bar front ends, delivering impressive height, straightforward installation, and confident off-road capability for a rugged, ready-to-tackle-anything ride.
- Lift height: 6" front and 4" rear lift, designed to accommodate 35" x 12.5" tires for enhanced ground clearance and traction.
- Knuckles included: New steering knuckles simplify installation by eliminating the need to drop upper control arms and preserve steering geometry.
- Three-piece sub-frame: Multi-piece design facilitates easier alignment and installation, reducing install time and complexity.
- Shocks not included: Factory shocks must be replaced with extended shocks for proper fitment; select extended shocks and boots in the options.
- Material and finish: Heavy-duty steel with black powder coat for durability and corrosion resistance in harsh environments.
- Bolt-on installation: Engineered for straightforward, bolt-on fitment with common tools, enabling a solid upgrade without complex fabrication.
- Warranty: Tuff Country backs this lift with a limited lifetime warranty, reflecting more than 25 years of suspension expertise.
- Compatibility notes: Designed for 2007–2010 4WD models with torsion-bar front ends; not compatible with coil-over front ends, StabilTrak, or dually configurations. Exhaust modification may be required on gas-engine models, and rims must have 4.5" backspacing or less.
The kit unlocks serious off-road capability while preserving daily-drive comfort. With a robust 6" front and 4" rear lift, you gain the clearance needed for challenging terrain, improved approach/departure angles, and the ability to run larger tires with confidence. The integrated knuckles and three-piece sub-frame maintain chassis rigidity and steering precision, while the bolt-on design keeps installation practical. Rely on Tuff Country’s heritage and the product’s lifetime warranty for a durable, value-focused upgrade.
