Smart, Simple Suspension Support for Commercial Builds

The SumoSprings® Solo kit is engineered for commercial vehicles—from service vans and utility trucks to fleet pickups—that need reliable load support without the complexity of air bags or helper springs. Whether you’re a distributor, upfitter or fleet manager, Solo delivers a maintenance‑free, bolt‑on solution designed for real‑world duty.

Engineered for Commercial Applications

When vehicles are fitted with equipment racks, tool storage, ladders, heavy cargo or trailer loads, the factory bump stop location simply wasn’t designed for that kind of stress. SumoSprings Solo bridges that gap with:

Progressive, adaptive support

The closed‑cell polyurethane spring compresses under load and rebounds as needed to reduce sag and improve control.

No air lines, no compressors, no adjustments

Install once and you’re done. Reduce service intervals, downtime, and potential failure points.

Improved ride quality and handling

Deliver better driver control, less body lean and fewer unexpected bottom‑outs—even on routes with frequent stops and heavy gear.

Built for harsh duty

Made in the USA, using microcellular polyurethane that resists UV, corrosion, moisture and extreme temperatures. Backed by a lifetime warranty.

SumoSprings Solo replaces bump stops with airless, load-adaptive support — without affecting ride comfort or suspension travel.

Ideal for Dealers, Upfitters & Fleet Operators

Whether you’re preparing vehicles for rental fleets, service contractors, municipalities or corporate builds, SumoSprings Solo offers real advantages:

- Simplified installation — Mounts in the factory bump stop location; no extra hardware, no custom fabrication.
- Reduced complexity — Replace traditional helper springs, airbags and oversized bump stops with a single SKU, making inventory management easier.
- Designed for duty cycles — Commercial vehicles run hard, often with shifting payloads and heavy loads. Solo is built for that reality.
- Partner‑friendly warranty and support — Your clients expect reliable performance; Solo supports that expectation with proven durability and backed performance.

Solo springs are built tough from the inside out — no maintenance, no metal fatigue, no compromise.

Commercial Use Cases

Built to Withstand the Toughest Environments
