Coil SumoSprings improve the load leveling ability of original equipment front and rear coil springs. Manufactured from micro-cellular urethane, the materials progressive spring rate with superior damping properties creates a cushion effect, enhancing capacity and ride comfort. They install by simply being slid between the turns of the coil spring.
I used these CSS coil sumosprings for a custom application in my car suspension. The 0.69-inch inner wall height was just what I needed for the extra support. Installation was straightforward, and they feel super sturdy!

Good but tricky to install
The CSS sumosprings work well for what I needed, but I did find the installation instructions a bit unclear. After a couple of tries, I got it to fit right. They perform nicely though!

Solid springs but arrived late
I'm pleased with the quality of these sumosprings from CSS. They seem durable and have good height at 0.69 inches. However, the shipping took longer than expected, which was a bit frustrating.

Not as described, disappointing
These sumosprings didn't meet my expectations. They looked different than what I saw online and the inner wall height felt off. I ended up returning them because they didn't fit my application like I hoped.
