Commercial‑Grade Load Support & Stability

Bolt‑On Helper Springs Built for Fleet, OEM, and Upfit Solutions

SuperSprings are engineered to strengthen your suspension system when payloads, trailers or heavy gear push factory setups beyond their comfort zone. Whether you're an OEM building service trucks, a distributor supplying upfitters, a fleet manager prepping vans or pickups, or a dealer supporting commercial applications, SuperSprings offer a maintenance‑free, bolt‑on solution built for professional duty.

Engineered for Real‑World Commercial Loads

When vehicles carry heavy gear, trailers, tools, water tanks, or modular bodies, the original leaf or coil springs often flatten out and sacrifice ride height, stability and control. SuperSprings step into that gap by offering:
Progressive, self‑adjusting support
The patented roller‑shackle design lets the helper spring activate only when needed, maintaining ride quality when empty and offering strong support when loaded.
Reduced sag, sway, and body roll
As loads increase, SuperSprings engage to stabilize the chassis, protect suspension components, and improve overall handling.
Simplified installation, no maintenance
Bolt‑on design means quicker fleet installs, less downtime, fewer failure points. No air lines, no compressors, no tuning.
Built for commercial duty
Made in the USA, using high‑grade materials engineered for business‑critical operation. Backed by a lifetime warranty so your clients can count on it.
How It Works

Built for Dealers, Upfitters, OEMs & Fleet Operators

For business customers, SuperSprings deliver real, measurable value:

● Faster turn-up & consistent installs — Upfitters and fleets benefit from standardized, repeatable installs that reduce variability and service callbacks.
● Reduced inventory complexity — One helper spring solution replaces multiple DIY add-ons, making SKU management simpler and service easier.
● Performance under duty-cycle stress — Designed for vehicles that run long hours, carry shifting loads, tow trailers, or are up-fitted for commercial use.
● Professional support & supply chain stability — A manufacturing partner experienced in commercial-grade builds, OEM integration, and aftermarket supply.

Built to Withstand the Toughest Environments

Typical Commercial Applications

Built to Withstand the Toughest Environments
● Service vans, utility trucks or pickups that carry gear, ladders, trailers, or modular bodies.
● Fleet vehicles used for delivery, utility, rental, construction, maintenance—where load and payload vary every shift.
● OEM builds of chassis-cab vehicles where upfit bodies add significant weight and change the ride dynamics.
● Trailers or tow-behind units where maintaining control, reducing sway, and protecting the chassis matter as much as curb appeal.
● Specialty vehicles or mobile service rigs needing predictable ride height, minimal maintenance, and consistent performance across multiple units.

Smarter Suspension Support, Without the Tradeoffs

Choose the Right SuperSprings Kit for Your Build

1. Identify the vehicle’s suspension base (leaf or coil), expected load profile, trailer/tow capacity, and duty cycle.
2. Choose the SuperSprings helper kit that matches your build: ensure correct length, capacity, fitment, and mounting design.
3. Install as part of your upfit or build – the bolt-on design simplifies integration and accelerates production or fleet turn-arounds.
4. Drive with confidence – your vehicle is now equipped with commercial-grade load support that helps reduce sag, enhance stability, and extend service life.

Shackle Adjustment

SuperSprings are designed with various shackles. The shackles will have 1, 2, or 3 bolt holes. The bolt holes allow the installer to adjust the SuperSprings. The higher the hole, the more pre-load tension, allowing the SuperSprings to start higher on the spring rate curve. Below is a chart showing the various bolt positions for a two-hole shackle.
