Product Description

The Tuff Country 55907KH 5-Inch Suspension Lift Kit is built for truck owners wanting serious clearance and a commanding stance on their 2005-2006 Toyota Tundra. With approximately 5" of front lift and about 4" in the rear, this kit allows larger tire packages (such as 33") while enhancing off-road capability and maintaining ride quality. The inclusion of heavy-duty steering knuckles and a one-piece subframe drop preserves suspension geometry under lift conditions.

Designed specifically for 2005-06 Toyota Tundra models in both 2WD and 4WD configurations, this kit pairs spacer technology, upgraded knuckles, and premium SX6000 rear shocks into a comprehensive bolt-on solution. While factory front struts may be reused in many setups, the rear shocks included ensure proper damping. Please note: fitment for 2007 and later model years or special trims is unverified, so vinyl checking your VIN and trim is strongly recommended before purchase.

After installation, an alignment is strongly recommended to correct camber, caster and toe. Verify your tire and wheel fitment - oversized tires may require brake-line extensions, sway-bar links or minor trimming. The kit is backed by a limited lifetime structural warranty, giving peace of mind to serious off-road builds. Professional installation is advised for best performance and safety.
