Product Details
Description
Raise your 2005–2006 Toyota Tundra with confidence using the Tuff Country 55907KH 5" Lift Kit with SX6000 Shocks. This complete suspension upgrade is designed for durability, value, and easier installation, delivering noticeable ground clearance and improved off-road capability without breaking the bank.
- Lift height: 5" front / 4" rear, designed to accommodate 33" tires for enhanced off-road traction
- Includes SX6000 shocks: Premium shocks are included to match the lift and provide a balanced ride
- Knuckles and one-piece sub-frame: Heavy‑duty knuckles and a single, reinforced sub-frame for added strength and consistent alignment
- Front struts retained: Front stock struts can be kept, simplifying installation and preserving steering feel
- Rear installation components: One-piece rear blocks and U-bolts ensure secure mounting and reliable setup
- Wheel and tire compatibility: Engineered for 33" x 12.5" tires; rims require 4.5" backspacing or less, and factory rims will not fit with this kit
- ABS and hub compatibility: Designed to fit ABS brakes and automatic hubs; optional ABS plugs available for non‑ABS applications
- Installation notes: Factory-length shocks must be replaced with extended rear shocks to install the kit properly; comprehensive hardware is included
- Warranty and support: Backed by Tuff Country’s limited lifetime warranty and supported by a long-standing brand with 35+ years of suspension expertise
This kit is purpose-built to deliver real-world improvements: increased ground clearance for challenging terrain, the ability to run larger tires for better traction, and a more commanding stance—all while maintaining a practical, serviceable upgrade path. The included knuckles, sub-frame, and front/rear hardware are designed to endure off‑road use, and the option to retain front struts helps preserve a comfortable daily drive. Backed by a trusted name in suspension, this Tuff Country kit provides a durable, value-driven solution for Toyota Tundra owners seeking reliable lift without compromise.
