Anti‑Sway Suspension Support for Trucks

Bolt‑On Stability Upgrade for Trucks with Rebels or Air Bags
SuperCoils are engineered to replace factory coil springs on trucks with a commercial-grade solution, providing progressive, maintenance-free support. Designed for fleet pickups, service trucks, contractor rigs, and off-road capable trucks, SuperCoils reduce sag, improve ride control, and enhance stability under heavy payloads, towing, or front-end mounted equipment like snow plows or brush guards.

PLEASE NOTE: Not intended for use on their own. Only to be used in tandem with air bags, or Rebel SumoSprings kits.

Engineered for Real-World Duty Loads & Towing

Trucks carrying trailers, airbag systems, or heavy front/rear equipment often experience a gap between the overload spring contact plate and the chassis—resulting in reduced stability, excessive sway, and compromised control. SuperSway Stops bridge that gap by:
Progressive foam insert design
Closed-cell polyurethane compresses under load and engages the overload spring faster, restoring stability and reducing body lean.
Works exclusively with Rebels or air bag setups
Designed specifically for trucks that have SumoSprings Rebels installed or an air bag system with auxiliary top-leaf overload springs.
Maintenance-free, bolt-on installation
No air lines, compressors, or adjustments; installs quickly in upfit bays or service shops.
Made in the USA, built for commercial use
Supports heavy-duty trucks and fleets operating under demanding conditions.
How It Works

Built for Dealers, OEMs, Upfitters & Fleet Operators

SuperSway Stops provide real business advantages:

● Faster vehicle turn-up — Simplified installation reduces downtime in upfit or fleet maintenance environments.
● Reduced service risk — Maintenance-free design ensures fewer callbacks and consistent performance.
● Inventory efficiency — One kit addresses common instability caused by disengaged overload springs in trucks with Rebels or airbags.
● Fleet reliability — Ensures consistent handling and improved driver confidence when towing or carrying heavy loads.
