SuperSprings are a simple, bolt-on, steel helper spring that eliminates rear-end sag and stabilizes sway & body roll. Built from high-grade shot peened steel, this suspension solution allows you to load up without sacrificing your ride quality. 

The SuperSpring includes a patented roller shackle on each end that allows for self-adjustment as weight is changed. This is particularly helpful as you add water, tools or heavy gear to your vehicle.

The SSA55 has an additional load leveling capacity of 1,900 lb.

Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

The Sumo Springs were very easy to install. The Super Springs were a little more difficult due to the need to compress the leaf spring but overall fairly straight forward. After installation the van rides much better. I was looking to reduce the sway on corners but did not want to loose the comfortable ride quality. Using thees achieved what I wanted to accomplish.

As with the Sumo Springs for the same vehicle, the quality and installation was great. Outstanding improvement to the ride and ride height.

The combination of Sumo and SuperSpring have made a great difference in the ride quality. They have basically eliminated body roll and soaks up potholes and large road depressions like they weren’t even there. The van rides like floating clouds

Really made a difference for limiting sway. It was difficult to clamp the two existing leafs, but once clamped, the installation went smoothly. It was unclear how far forward the front end of the new spring could go to the slot in the body. They seem to work well.

Huge difference in driving quality between the stock bump stop and sumo springs. We went from bumpy ride and feeling every pot hole to better ride quality. Before the sumo springs every high wind areas we passed I have to slow down and manage the steering wheel continuously, After the install, it's much stable and resists cross winds immediately and consistently adjusting the vehicle position in space. Probably the best investment I put on our 2020 Airstream Interstate 19.

Great product with even better support. Install was a breeze, even with tuning the support level with my trailer.

Shipping was fast and received parts in few days to Toronto Canada, waiting for a warm dry day to install the complete systems

I have just completed installation of this on my Sprinter 3500 based motorhome. It is a quality product that has helped improve the ride and helped raise the back nearly 3/4". I would recommend this product to anyone with this type of vehicle, due to the constant heavy loading of the vehicle itself. I will admit this was a challenge to install this on the 3500 van due to the strength of the existing leaf springs on the 3500. However, with the guidance and supervision of the SuperSprings team, especially Mark, I was able to safely install this myself. He even noted a potential positioning error I had made which would have led to interference with the frame that was easily corrected. I really appreciate that level of support and concern from them.

Very well designed and built. The high quality is evident from the first time you handle the product. The installation instructions are well thought out and easy to follow. Tech support is easy to reach if a problem arises. By adjusting the bolt location on the spring shackles, you can tune the leaf springs to work optimally with Sumosprings and your expected load. With few exceptions, this is a top notch product.
