Product Details
Description
Upgrade your 1999–2003 Toyota Tundra with the Tuff Country 55905 5-Inch Lift Kit. This no-shocks kit is designed for both 2WD and 4WD Tundras, delivering added ground clearance, strengthened suspension parts, and a straightforward path to bigger tires without breaking the bank.
- Lift Height: 5" front lift and 4" rear lift, engineered to fit up to 33" tires for enhanced off-road capability.
- One-Piece Sub-Frame: A single, rigid sub-frame designed to increase overall strength and durability under load and during aggressive terrain.
- Knuckles & Upper Joints: Heavy‑duty replacement knuckles with upper ball joints and bearings pressed into new spindles for solid steering geometry.
- Rear Suspension: Includes rear blocks and U-bolts to complete the lift and maintain solid axle support.
- Shocks Included: No shocks are included in this kit; factory length shocks must be replaced with extended rear shocks for proper installation.
- ABS & Wheel Compatibility: Designed to work with ABS brakes and automatic hubs; vehicles without ABS require optional ABS plugs. Rims with 4.5" backspacing or less are required; factory rims will not fit.
- Front Struts: Front stock struts can be retained, helping preserve a near-factory ride while gaining height.
- Installation Notes: Designed specifically for 1999–2003 Toyota Tundra 2WD/4WD; heavy-duty components and spacers maintain alignment and improve rigidity during off-road use.
- Warranty & Support: Backed by a limited lifetime warranty from Tuff Country and supported by a leading retailer with expert knowledge and service.
- Included Hardware & Build: Comprehensive kit with knuckles, sub-frame, rear blocks, U-bolts, brackets, spacers, and essential hardware to complete the upgrade (no shocks).
This Tuff Country lift kit is built for real-world use—from daily driving to trail adventures—providing meaningful gains in ground clearance, tire clearance, and chassis stiffness. The combination of a robust one-piece sub-frame, carefully engineered knuckles, and precise spacers ensures a more confident stance and improved capability without compromising everyday drivability. If you’re after a value-driven upgrade that supports larger tires and durable construction, this kit offers proven performance and lasting support.
