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 SSA28 has an additional load leveling capacity of 1,500 lb.

Parts were as described and made of high quality material. Took 25 minutes to figure out how to install the first one by reading instructions step by step, the other side took 5 minutes only. It provided my truck much more strength to the leaf springs I already had. Now I am hooking up the trailer without having the truck lowering at all. And it rides so smooth. I dare to say this are better than air bags, plus slightly cheaper and 85% easier to install. Beside this seems to be a last forever item vs air bags that can deteriorate, crack or burst after 5 years. Trust me, you can’t go wrong with these super springs.

I can definitely feel an improvement with the springs on the back. I’m looking forward to pulling my new boat now and not having to deal with the bed of my truck sagging.

I have installed these on 2 Chevy Cube vans which haul a fair amount of weight - I like that it does not change the ride like air bags. I decided to install on my personal vehicle.
