Product Details
Description
The Tuff Country 55902KN 4.5" Lift Kit is a complete, bolt-in suspension upgrade designed for the 2005–2006 Toyota Tundra (2WD and 4WD). It delivers a balanced, level stance with a 4.5" front lift and a 3" rear lift, paired with SX8000 shocks for confident on- and off-road performance. Backed by a limited lifetime warranty, this kit is built for durability and long‑term value.
- Lift Height: 4.5" front and 3" rear to achieve a level stance on the 2005–2006 Toyota Tundra (2WD/4WD).
- Non-Knuckle Design: Rear blocks and U-bolts provide the level ride without knuckle modifications.
- One‑Piece Sub-Frame: Enhances overall strength and durability for daily driving and rough terrain.

- Stock Front Struts Retained: Simplifies installation and preserves familiar front-end feel.
- Shocks Included: SX8000 nitro gas shocks deliver controlled damping for improved ride quality and handling.
- New Ball Joint Included with an upper ball joint spacer to maintain proper steering articulation and alignment.
- Tire Clearance: Supports up to 33" x 12.5" tires; note that factory rims will not fit—use rims with 4.75" backspacing or less.
- Material & Finish: Heavy‑duty steel with a durable black powder‑coat finish for corrosion resistance.
- Warranty: Limited lifetime warranty protects your investment across the kit’s lifespan.
- Vehicle Fitment: Specifically engineered for 2005–2006 Toyota Tundra 2WD and 4WD applications.
This lift kit is ideal for drivers who want improved ground clearance and the ability to run larger tires without sacrificing ride quality. The combination of a strengthened non-knuckle design, reinforced sub-frame, and included SX8000 shocks offers a reliable upgrade for tackling dirt roads, trails, and everyday pavement. With practical installation considerations and clear rim-backspacing requirements, it’s a thoughtful, long‑term suspension solution for the Toyota Tundra enthusiast.
