Tuff Country 14990 4" Lift Kit with Knuckles and 1 Piece Sub-Frame No Shocks
Product Details
Description
The Tuff Country 14990 4" Lift Kit is a bolt-on suspension upgrade designed for 2001–2006 Chevy Silverado 3500 and GMC Sierra 3500 4WD trucks. Built for durability and value, it lifts the front and rear for a balanced stance and improved capability, backed by a limited lifetime warranty.
- Front/Rear Lift: 4" front and 2" rear lift (leveling front with rear) to provide substantial clearance while preserving ride quality.
- New Steering Knuckles: Eliminates the need to drop upper control arms, simplifying installation and maintaining steering geometry.
- One-Piece Sub-Frame: Adds rigidity and reduces squeaks and rattles for a steadier, more confident ride.
- Tire Compatibility: Enables use of 33" x 12.5" tires for enhanced traction and ground clearance.
- Shocks Included: Without Shocks — factory length shocks must be replaced with extended shocks to install properly. Shocks and boots can be added as an option if you haven’t already purchased extended shocks.
- Warranty: Supported by Tuff Country’s Limited Lifetime Warranty for long-term peace of mind.
- Quality and Origin: Made in the USA, reflecting Tuff Country’s 25+ years of suspension expertise.
- Installation Time: Approximately 8–10 hours with a straightforward bolt-on approach for skilled DIY enthusiasts or professional installers.
- Vehicle Fitment Notes: Fits 2001–2006 Chevy Silverado 3500 4WD and 2001–2006 GMC Sierra 3500 4WD; not compatible with dually models or Stabilitrak-equipped trucks. A rim with 4.5" backspacing or less is required; factory rims may not fit with this kit.
This kit is ideal for drivers who need genuine off-road capability, larger tire clearance, and a stronger front-end assembly without sacrificing the reliability you expect from a heavy-duty pickup. It’s a practical upgrade for daily drivers who tow, haul, or regularly tackle rough terrain, delivering a more commanding stance, improved ground clearance, and dependable performance across a wide range of conditions.
