  • Durable Steel Construction :: This kit is built with heavy-duty, powder-coated steel designed to endure demanding conditions. It provides long-lasting performance for both on-road and off-road applications while helping to maintain vehicle stability by increasing stiffness.
  • Increased Load Capacity (Up to 500 lbs) :: The kit enhances the vehicle’s rear suspension, allowing it to support an additional weight of up to 500 lbs. It is perfect for towing or carrying heavy cargo without the need for a complete spring pack replacement. Specifically designed for small trucks and SUVs, this solution is ideal for vehicles that carry heavy loads or tow trailers.
  • Improved Ride Stability and Comfort :: By reducing rear-end sag, the kit stabilizes the vehicle under heavy loads and enhances ride quality—especially when towing trailers or hauling gear. It contributes to consistent and controlled suspension performance, maintaining a level ride height, minimizing body roll and sway, and improving overall driving stability during lane changes or cornering.
  • Progressive and Tunable Load Support :: The kit features a progressive design that evenly distributes the load across the suspension. It offers adjustable support, allowing users to customize the suspension settings to match their specific load requirements for optimal performance.
  • Easy Installation :: This kit is straightforward to install, requiring minimal modifications.

Everything is fine, just I couldn't find an extras nuts 🔩 to double nutty the U bolts, so I ended up getting the whole new set of U bolts.

Specifically for small trucks with a 2.5 inch springs. Needed a small lift on my 2024 Toyota Tacoma to add some extra weight to be carried by the trailer hitch. I thought I would give this support spring a try. I can report that it did increase my weight carrying capacity by an estimated 250 to 500 lbs. Adding the spring raised the hitch drop about 1 1/2 inch and provided less bounce when towing the trailer. What I did not like is that it is only on one side of the spring which places additional stress on one side of the spring pack. I works for its designed and intended purpose and it is very easy to install. That is the reason I gave it 4 stars. But I think I will look into a full extra spring that will provide equal pressure on both sides of the spring pack.
