Tuff Country 16090 6" Lift Kit with Knuckles and 3 Piece Sub-Frame No Shocks
Product Details
Description
The Tuff Country 16090 6" Lift Kit is a rugged, value-focused suspension upgrade designed for 2011–2019 Chevy Silverado 3500 4WD and 2011–2018 GMC Sierra 3500 4WD. Built around knuckles and a 3-piece sub-frame, it delivers substantial tire clearance and a confident, off-road ready stance with durability you can trust.
- Lift Height: 6" front / 4" rear lift to accommodate larger tires and improve ground clearance.
- Front Knuckles: Integrated knuckles eliminate the need to drop upper control arms, simplifying installation and maintaining steering geometry.
- 3-Piece Sub-Frame with Skid Plates: Heavy-duty, modular sub-frame design paired with skid plates for undercarriage protection.
- Relocated Bump Stops: Front and rear bump stops are adjusted to optimize suspension travel and ride height.
- Tire Compatibility: Engineered to support up to 35" x 12.5" tires for improved off-road capability.
- Shocks Not Included: Sold without shocks; factory shocks must be replaced with extended shocks for proper fit. Shocks and boots are available in the options.
- Rim Backspacing Note: Requires rims with additional backspacing; exact backspacing varies with rim size—follow the included instructions for proper sizing.
- Installation Time: Average 8–10 hours for a complete, quality installation.
- Warranty: Backed by Tuff Country’s limited lifetime warranty for lasting confidence in your upgrade.
- Application Note: Specifically designed for 2011–2019 Silverado 3500 4WD and 2011–2018 Sierra 3500 4WD; will not fit dually models.
With this lift kit, you gain more tire clearance for rugged terrain and a more commanding on-road presence without compromising chassis integrity. The front knuckles preserve steering feel while the 3-piece sub-frame and skid plates shield critical components during difficult trails. Relocated bump stops improve suspension travel, contributing to a smoother ride over rough surfaces. To complete the setup, plan for extended shocks and compatible boots, and choose rims with the appropriate backspacing to ensure a proper, safe fit. Backed by a long-standing brand and a lifetime warranty, this kit offers a reliable path to a higher, more capable Silverado 3500 or Sierra 3500.
