BOOM & CRANE TRUCKS

Factory suspensions aren’t built for the constant, uneven weight of cranes, welders, and tools, causing sag, lean, and body roll. SuperSprings International solves this with airless, maintenance-free SumoSprings and SuperSprings helper springs that deliver progressive support to keep boom and crane trucks level, stable, and job-ready.

Support When You Need It. Stability When It Matters Most.

SMARTER SUSPENSION FOR EVERY BUILD

Boom and crane trucks operate under constant, uneven loads — toolboxes, welders, compressors, and cranes that shift the vehicle’s balance and strain factory suspension.

SumoSprings are engineered from microcellular polyurethane that adapts to every condition. Lightly loaded, they absorb vibration and road chatter. Under heavy or offset weight, they compress progressively — reducing sag, stabilizing sway, and keeping your truck level and controlled. It’s the simplest way to add professional-grade suspension performance without air systems, maintenance, or compromise.

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.
