Lifting or modifying your Tundra’s suspension can throw off axle geometry, leading to handling instability and premature component wear. This adjustable rear suspension kit corrects alignment issues, ensuring your truck remains stable, responsive, and optimized for any terrain. Designed for Toyota Tundra owners who demand precision handling, durability, and off-road capability, this rear suspension upgrade is a must-have for lifted and performance-driven builds.
Two-Stage Powder Coating for Superior Durability
Our two-stage powder coating process provides long-lasting corrosion resistance. Each component is coated with a zinc primer base coat for rust protection, followed by a tough topcoat in your choice of 10 colors.
Proudly Made in the USA
Manufactured in Orem, UT, our CORE 4X4 components are built to exacting standards, ensuring premium craftsmanship, quality control, and long-term reliability.
Optional Hardware Upgrade
This kit installs using factory hardware, but for those dealing with worn or rusted bolts, we offer an optional Grade 8 hardware kit, available separately, for a secure and hassle-free installation.
