Product Details
Description
The Tuff Country 16961 6" Lift Kit with Knuckles and 3 Piece Sub-Frame is a bolt-on suspension upgrade engineered for the 2006 GMC Sierra 1500 4WD. It delivers substantial ground clearance and a bold stance, while integrating components that simplify installation and maintain solid handling.
- Lift Height: 6" front and 5" rear lift for a pronounced, capable stance and improved off-road clearance.
- Knuckles & Sub-Frame: New steering knuckles eliminate the need to drop upper control arms; a three-piece sub-frame aids alignment and eases the installation process.
- Simple Bolt-On Installation: Designed for straightforward assembly with a multi-piece sub-frame to streamline the build.
- Lateral Compression Arms: Included to help stabilize the suspension through rough terrain and maintain precise alignment.
- Tire Compatibility: Supports up to 36" x 12.5" tires, expanding traction and style opportunities for your Sierra 1500.
- Finish & Material: Black powder-coated steel construction for durability and corrosion resistance in varied driving conditions.
- Shocks Requirement: Factory-length shocks must be replaced with extended shocks to install properly; shocks and boots should be selected in the Options if not already owned.
- Rim Backspacing: Requires rims with 4.5" backspacing or less; factory rims may not fit this lift kit.
- Warranty: Backed by Tuff Country's limited lifetime warranty for long-term confidence.
With this kit installed, your Sierra 1500 gains meaningful ground clearance for challenging trails, enhanced approach/departure angles, and the opportunity to run larger tires for improved traction and presence. The knuckles and three-piece sub-frame are designed to simplify setup and maintain stable steering, while the rugged black finish and steel construction promise durability. Backed by a legacy of more than 25 years in suspension, this lift kit offers a reliable upgrade paired with a lifetime warranty for lasting peace of mind.
