SuperSprings are an innovative, self-adjusting suspension stabilizing system engineered by SuperSprings International to reduce rear-end sag, enhance load support, and minimize body roll without the complexity of air lines or constant tuning.
Designed to mount above your vehicle’s factory leaf springs, these suspension stabilizers automatically activate when your leaf packs flex under load—thanks to patented anti-friction rollers that engage under tension for seamless support.
Crafted from shot-peened SAE 5160H alloy steel right here in the USA, SuperSprings deliver exceptional durability and longevity under rugged conditions.
The system works progressively, stiffening only as needed, so your ride remains smooth and comfortable when unloaded, but firmly controlled when loaded or towing.
As your vehicle carries cargo or a trailer, the progressive blade design shares the load with your factory springs, reducing bottoming out and improving handling—even in crosswinds and on rough roads.
Installation is straightforward and bolt-on with adjustable shackles that let you dial in the correct preload and tune for lift or leveling if necessary.
Once installed, the SuperSprings stabilizer works continuously without maintenance, offering a long-term suspension upgrade backed by SuperSprings International’s proven engineering.
These SuperSprings were specifically designed for your 2004-2025 Sprinter 2500, ensuring a perfect fit and maximum reliability.
These SuperSprings support up to 1900 lb of weight at 50% compression.
By reducing body roll by up to 30%, this helper spring system improves driver control, confidence, and safety under real-world hauling scenarios.
For heavy-duty trucks, work vans, motorhomes, and performance builds, SuperSprings give you reliable load leveling and sway control without compromise.
