Upgrade the performance and stability of your All-New Toyota Hilux 2023–Current (Workmate, SR, SR5, SR5+, GR Sport) with the RoadActive Suspension (RAS) Heavy Duty Leaf Spring Assist Kit. Engineered for vehicles that carry heavy loads or tow regularly, this system reinforces your rear leaf springs without compromising your factory ride comfort.
Designed for strength, reliability, and ease of use, the 4611-TDHD kit delivers immediate improvements to stability, handling, and load support—whether the truck is empty or fully loaded. Installation is quick, requiring no ongoing adjustments or maintenance.
Note: Vehicles equipped with self-levelling headlights will require a simple sensor relocation at the rear leaf. (Top 16mm, bottom 5mm—see listing photos.)
