Construction

SMARTER SUSPENSION FOR EVERY JOB

Support When the Load Hits Hard

SumoSprings are made from micro-cellular polyurethane that delivers dynamic support right when you need it most. As the load increases — whether you’re hauling gravel, tools, or heavy machinery — SumoSprings compress and push back progressively, reducing sag, smoothing harsh hits, and controlling sway.

Unlike airbags or metal helpers, there’s nothing to adjust, refill, or maintain. They adapt automatically to changing loads, giving you a stable, predictable ride no matter how uneven the workday gets. It’s the simplest way to toughen your suspension without sacrificing comfort or control.

What Our Customers Are Saying

My 2017 Hyundai SF is a great SUV with the only complaint I’ve had is the rear suspension seems underside and appears to easily bottom out. I had the Coil SumoSprings installed and they made a noticeable improvement when pulling a 21′ boat.

Scott

2017 Hyundai Santa Fe

I just did a 900-mile ski trip from South Carolina to West Virginia in my 2017 Dodge Journey. With the car packed to the roof and skis on the rack, the rear Coil SumoSprings made a huge difference — cutting down sag, improving stability, and reducing body roll on curvy mountain roads. Install took some effort, but it was worth it. I’ve already ordered the front set to complete the setup.

Clarkson

2017 Dodge Journey

Bought a pair of the CSS-1195 for my 2018 Toyota Sienna XLS AWD. Very easy to install the SumoSpring for the front suspension. Noticeable improvements of the body roll reduction at the corners, which leads to better handlings and driving experience. Very satisfied with the purchase.
