Upgrade your 3rd gen Tundra with a true TRD-based suspension conversion that delivers aggressive stance, improved ride quality, and factory-level geometry. This preload collar lift kit is engineered specifically for 2022–2026 Toyota Tundra models equipped with standard rear coil suspension. Designed to work with Toyota TRD shocks and struts, this system provides a true 3? of front lift and 1.5? of rear lift while maintaining proper alignment and factory suspension characteristics. This is not a traditional spacer lift — ride quality and geometry are retained without the need for new upper control arms.
