Public Transit

Here’s a combined, shortened version that keeps the key points clear and strong: **Public transit vehicles face constant stops, heavy passenger loads, and daily urban routes — stresses factory suspension wasn’t built for. The result is rear sag, uneven ride height, and increased body roll that reduce comfort, accelerate wear, and hurt efficiency. SuperSprings International provides engineered suspension solutions for vans, shuttle buses, commuter vehicles, and medium-duty trucks to keep fleets level, stable, and road-ready mile after mile.**

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.
