  • Compatibility: Fits 1999–2006 Toyota Tundra 4WD; rear axle only

This kit provides a robust, reliable 4-inch rear lift that improves clearance for larger tires and helps level the vehicle under load. By using tapered cast blocks and corrosion-resistant zinc-coated hardware, it minimizes driveline vibrations and ensures lasting performance in all weather. The bolt-on design means installation can be completed with basic hand tools, and the use of extended u-bolts preserves factory alignment when upgrading the rear suspension. Note that front axles should not use lift blocks, and longer shocks are often necessary when using blocks of 2" or greater.
