Tuff Country 16994 6" Lift Kit with Knuckles and 3 Piece Sub-Frame No Shocks
Product Details
Description
Tuff Country 16994 6" Lift Kit with Knuckles and 3 Piece Sub-Frame is a bolt-on suspension upgrade tailored for 2007–2010 Chevy Silverado 3500 4WD. Designed for drivers who want extra ground clearance and the ability to run larger tires, this kit pairs rugged steel construction with a straightforward installation that helps you get back on the road quickly.
- Lift Height: 6" front / 4" rear for a commanding, balanced stance
- Knuckles Included: New steering knuckles eliminate the need to drop upper control arms
- Sub-Frame: Multi-piece 3-section sub-frame for easier, cleaner installation
- Finish: Black powder coat for durability and corrosion resistance
- Tire Compatibility: Supports up to 35" x 12.5" tires
- Shocks Included: Without shocks — factory-length shocks must be replaced with extended shocks (select options for shocks and boots)
- Drivetrain & Fitment Notes: Fits 2007–2010 Silverado 3500 4WD with torsion-bar front end; will not fit coilover front ends or Stabil Trak-equipped models
- Rim & Exhaust Considerations: Factory rims may require a rim with 4.5" back spacing or less; exhaust modification may be required on gas-engine models
- Warranty: Limited lifetime warranty backed by Tuff Country
- Estimated Install Time: Approximately 8–10 hours
- Material: Heavy-duty steel designed for longevity under demanding use
This 6" lift kit unlocks serious off-road capability while preserving overall handling and compatibility with 35-inch rubber. The included knuckles and three-piece sub-frame reduce installation complexity and help align steering geometry for reliable performance. With a durable black powder-coated finish, the kit resists road debris and weather exposure, keeping your Silverado looking and performing like new longer. Shocks are not included by design, so choose extended shocks (and boots) in the options to complete the setup. If you’re upgrading your 2007–2010 Silverado 3500 4WD for bigger tires, this kit delivers a solid, value-driven solution with Tuff Country’s trusted engineering and lifetime warranty.
