The Tuff Country 54075KH 4" Uni-Ball Lift Kit with SX6000 Shocks is a purpose-built suspension upgrade for 2007–2021 Toyota Tundra owners who want more ground clearance and improved on- and off-road capability without sacrificing ride quality.
- Lift Height: 4" front / 2" rear lift to level the stance and increase wheel travel.
- Uni-Ball Upper Control Arms: built-in Uni-Ball joints with teflon-lined FK uni-ball joints for 30–35% more articulation and reduced binding compared with standard ball joints.
- Strut Spacers: strategically placed spacers maintain near factory ride characteristics while delivering added ground clearance.
- Shocks Included: SX6000 shocks are included to provide durable, consistent damping on and off road.
- Installation Notes: no drilling, cutting, or welding required; front struts can be retained; factory length shocks must be replaced with extended rear shocks to install the kit properly.
- Wheel Backspace & Tire Considerations: designed for a wheel with approximately 5.5" backspacing reduction; stock tires and wheels can be used, but wider tires on stock wheels may contact the upper control arm.
- Fitment: engineered for 2007–2021 Toyota Tundra 2WD and 4WD models (excludes TRD Pro).
- Made in the USA & Warranty: proudly made in the USA with a limited lifetime warranty for lasting peace of mind.
