Description
Upgrade your Toyota Tundra with a 4-inch lift that preserves ride quality while expanding off-road capability. From a brand with 35+ years of suspension expertise, the 54070KN kit combines upper control arms, strut spacers, and SX8000 shocks for an easy bolt-in upgrade backed by a lifetime warranty.
- Lift Height: 4 inches of front lift to boost ground clearance and off-road stance.
- Shocks Included: SX8000 nitro gas shocks (rear) for a controlled, stable ride on trails and highways.
- Upper Control Arms: New upper control arms maintain factory geometry for improved steering and alignment after lifting.
- Strut Spacers: Strut spacers help preserve ride quality by keeping damper performance in the lifted range.
- Install Type: Bolt-in design with no drilling, cutting, or welding required for straightforward installation.
- Tire Fitment: Supports 33" x 12.5" tires (no trimming) or 35" x 11.5" tires (minor trimming of body mounts); wheel backspacing of 5.5". Stock tires and wheels can be used; wider tires on stock wheels may contact the upper control arm and are not recommended. Excludes TRD Pro models.
- Warranty: Limited lifetime warranty from Tuff Country for long-term confidence.
- Made In: Proudly Made in the USA, reflecting durability and quality standards.
- Vehicle Fitment: Specifically designed for 2007–2021 Toyota Tundra 2WD/4WD; does not fit TRD Pro models.
This lift kit is engineered to deliver real-world benefits: higher ground clearance for challenging terrain, the ability to run larger tires for enhanced traction, and preserved steering feel thanks to the included upper control arms. The simple bolt-in installation saves time and keeps your truck ready for weekend adventures or daily driving, while the SX8000 shocks help maintain a balanced, factory-like ride both on and off the pavement.
