SumoSprings from SuperSprings International is the ultimate air-bag alternative built to deliver smarter suspension support for real-world loads.
Rather than relying on airlines, compressors, or constant adjustment, SumoSprings utilize a one-piece, closed-cell microcellular polyurethane spring that compresses progressively as weight shifts—reducing rear-end sag, improving ride height, and enhancing stability without extra maintenance.
This innovative airless helper spring provides smoother, safer handling by absorbing impact and dampening sway, giving you more confidence behind the wheel.
Crafted to endure, SumoSprings resist corrosion, UV exposure, moisture, and extreme temperatures, and are covered by a lifetime warranty.
Thanks to their microcellular polyurethane construction, they deform under load but rebound reliably, delivering consistent support mile after mile.
As a plug-and-play suspension upgrade, they install neatly where your factory bump-stop sits for an efficient install with no moving parts, leaks, or compressors.
Whether you’re towing an RV or trailer, hauling heavy cargo in a work van, or tackling off-road terrain, SumoSprings adapt automatically to weight changes—keeping your vehicle level, stable, and predictable.
These SumoSprings are specifically designed for your 2014-2025 RAM ProMaster 1500/2500/3500 (2WD Only), ensuring a perfect fit and maximum reliability.
At 50% compression, these springs support an additional 1000 lb of weight.
Unlike traditional airbags that require constant attention or steel helper springs that can wear out, SumoSprings offer a self-adjusting, maintenance-free suspension support solution.
If you’re looking to reduce sag, eliminate sway, and improve load stability while towing or hauling, SumoSprings provide durable, long-lasting ride control that’s truly built for the journey.
