Police vehicles don’t live an average life — loaded with cages, gear, electronics, and armor, they put constant stress on factory suspension, leading to sag, sway, and unpredictable handling during high-speed maneuvers or hard braking. SuperSprings International solves this with suspension solutions that keep pursuit vehicles, SUVs, and trucks level, stable, and responsive, giving officers the control they need and fleets the reliability they expect.

Built for the Call. Trusted Every Mile.

Everything your
police fleet needs for stable handling, consistent control, and zero maintenance — without the complications.

Support When You Need It. Stability When It Counts.

SMARTER SUSPENSION FOR LAW ENFORCEMENT FLEETS

Police vehicles are pushed to their limits — loaded with partitions, weapon racks, electronics, and armor, all while performing at high speeds and over unpredictable terrain. Factory suspension wasn’t built for that kind of demand.

SuperSprings helper springs automatically adapt to changing weight and load, keeping vehicles level and stable through every shift. They reduce sag, sway, and body roll without affecting everyday ride quality — giving officers better control and fleets greater consistency across every vehicle.

No air systems. No maintenance. No downtime. Just reliable, American-built suspension that keeps your fleet ready for duty, every day.

A SIMPLE UPGRADE WITH SERIOUS SUPPORT

PERFECT FOR PURSUIT-RATED VEHICLES LIKE THE FORD EXPLORER AND CHEVROLET TAHOE
Coil SumoSprings are a drop-in suspension enhancement for coil-sprung police vehicles — designed to add progressive load support without altering factory ride comfort or handling.

They install easily inside the factory coil springs, automatically adjusting to changing loads from partitions, gear, and electronics. The result is a level, more controlled stance that improves stability, reduces sag, and cuts down on body roll during high-speed maneuvers or sudden turns.

No air systems. No adjustments. No maintenance. Just a dependable, bolt-in solution trusted by police fleets and upfitters nationwide — built to perform shift after shift, 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.
