Dump trucks

Dump trucks aren’t built for comfort — they’re built for work. But stock suspensions struggle under constant loading and dumping, causing sag, sway, and harsh rebound. SuperSprings International solves that with adaptive, maintenance-free solutions that automatically adjust to changing weight, keeping your dump truck level, stable, and controlled — whether fully loaded or running empty.

Support When You’re Loaded. Comfort When You’re Not.

SMARTER SUSPENSION FOR EVERY JOB

SumoSprings are built for the daily grind of dump truck duty — full loads in the morning, empty runs by afternoon. Made from micro-cellular polyurethane, they compress progressively under weight, delivering the right amount of support exactly when it’s needed.

When loaded, they reduce rear-end sag and stabilize sway. When empty, they soften the ride and absorb harsh rebound. It’s a simple, maintenance-free upgrade that keeps your dump truck balanced, controlled, and comfortable — no air systems, no downtime, no compromise.
