Product Details
Description
Raise your Chevy Silverado 1500HD or compatible GM 4WD trucks with confidence using the Tuff Country 14992 4" Lift Kit. This bolt-on system brings substantial height, expanded tire options, and durable construction designed for real-world use on GM pickups and SUVs from 2001–2006.

- Sub-frame: Multi-piece 3-piece sub-frame designed to simplify installation
- Compatibility: Supports up to 33" x 12.5" tires on eligible rims
- Material & finish: Steel components with black powder coat for durability and corrosion resistance
- Shocks included: Not included; factory-length shocks must be replaced with extended shocks for proper fitment

- Warranty: Limited lifetime warranty from Tuff Country
- Fitment notes: Not compatible with Stabil Trak; rim backspacing should be 4.5" or less
This kit is built for real-world use: it enables larger 33" tires to broaden traction and ground clearance for dirt roads, gravel drives, and light off-road adventures, while preserving the vehicle’s factory geometry where possible. The combination of knuckles, a three-piece sub-frame, and reinforced brackets delivers a solid, engineered upgrade that’s easier to install than traditional, multi-piece systems. With its durable steel construction and black powder coating, the components are designed to withstand road salt, mud, and year-after-year use. Ideal for Silverado 1500HD and Avalanche 2500 owners who want a confident, capable stance without compromising daily drivability.
