Tuff Country 55907 5" Lift Kit with Knuckles 1 Piece Sub-Frame Rear Blocks and U-Bolts No Shocks
Product Details
Description
Upgrade your 2005–2006 Toyota Tundra with a purpose-built, value-forward 5-inch suspension lift. This Tuff Country 55907 kit delivers solid off-road capability while preserving ride quality, designed for Tundra owners who want a reliable, long-lasting lift without dealership price tags.
- Lift Height: 5" front / 4" rear lift to accommodate larger tires and enhance ground clearance.
- Inclusion of Knuckles and One-Piece Sub-Frame: Heavy-duty replacement knuckles and a single, reinforced sub-frame for added strength and improved alignment stability.
- Shocks Not Included: Kit is sold without shocks; factory shocks must be replaced with extended rear shocks for proper installation. Shocks/boots available in options.
- Front Struts Retainable: Front struts can be kept in place, simplifying installation and maintaining a familiar steering feel.
- Upper Coil/Strut Spacers: Maintain a near-factory ride height and feel while gaining height for larger tires.
- ABS Compatibility: Designed to work with ABS-equipped Tundras; vehicles without ABS may require optional ABS plugs.
- Rim and Tire Compatibility: Supports 33" tires and requires rims with 4.5" backspacing or less; factory rims won’t fit with this lift kit.
- Rear U-Bolts, Rear Blocks, and Hardware: Complete hardware kit includes rear blocks and U-bolts for secure, durable installation.
- Quality Construction: Built by Tuff Country, a brand with 25+ years of suspension experience and a reputation for value-driven, reliable upgrades.
The 5-inch lift opens up 33" tire readiness, giving you improved approach and departure angles for off-road trails while preserving a comfortable, controlled daily-drive feel thanks to the integrated spacers and reinforced sub-frame. This kit is ideal for Tundra owners wanting a robust, long-lasting lift that pairs well with ABS brakes and modern wheel setups, and it’s backed by Tuff Country’s limited lifetime warranty for lasting peace of mind.
