Heavy-Duty Coil Spring Upgrades

Restore lost ride height. Eliminate bottoming out. Drive confidently — even under heavy loads.

Coils That Carry the Load

Stronger than spacers. Smarter than stock. SuperCoils are built to carry real-world loads with confidence.

Higher Spring Rate

Engineered to support added weight like plows, armor, or upfits without sagging or squatting.

Restores Lost Ride Height

Recovers original ride height lost to sagging springs and keeps it — even under load.

Improved Handling & Braking

Better chassis control under load means safer turns, more responsive braking, and less sway.

Built to Last

Shot-peened steel, corrosion-resistant finish, and lifetime durability — made in the USA.

How It Works

True Coil Spring Strength — Not Just a Spacer Fix

SuperCoils are a direct replacement for your factory coil springs, but with a much higher spring rate and heavy-duty construction. Unlike spacer kits that merely lift the vehicle, SuperCoils actually carry the load — helping you maintain proper suspension geometry, ride height, and handling over time.

As you add equipment or cargo, SuperCoils resist sag and bottoming out, providing consistent performance without harshness. No gimmicks, no band-aids — just a smarter spring built for demanding use.

Why It Lasts

Engineered for Load-Bearing Longevity

Made in the USA, backed by a lifetime guarantee

SuperCoils are built from premium, shot-peened steel to reduce internal stress and improve long-term durability. A corrosion-resistant powder coat protects them from road salts, mud, and harsh jobsite environments.

Every SuperCoil is rigorously tested to ensure it holds up to repeated compression and rebound cycles without degrading. No squeaks, no sags, no surprises — just steady, reliable support for years to come.

No Shortcuts. No Compromises.

Why SuperCoils Beat Spacer Kits

Spacer kits may raise your vehicle, but they do nothing to strengthen the spring — meaning the weak stock coil still carries all the load. Over time, that means renewed sag, harsh bottom-outs, and a compromised ride.

SuperCoils solve the problem at its root by replacing the spring itself. You get higher spring rate, restored ride height, and predictable handling whether loaded or empty. No added stress on other components. Just true suspension improvement that lasts.

Built for Constant Load. Trusted Nationwide.

Confidence for Work Trucks, Vans, and Overlanders

Why SuperCoils Are a Pro’s First Pick

SuperCoils are trusted by fleets, commercial upfitters, and everyday drivers who need long-term strength in challenging conditions. With heavy-duty construction and no moving parts to service, they’re a dependable solution for vehicles that face constant weight, tough roads, and mission-critical uptime

Built for Loaded Rigs, Front to Back

SuperCoils come in multiple configurations to match front and rear coil applications across popular work and recreational vehicles. Whether you’re adding weight up front or in back, they deliver confident support where it counts.

Perfect for:
✅ Snowplow trucks with blade setups and front gear
✅ Service vans with full upfits and shelving
✅ Overlanders with winches, bumpers, and tents
✅ Utility trucks with tanks, generators, and tools
✅ SUVs or pickups towing or hauling frequently

No more squat, sag, or bounce — just steady control and confidence on every job or journey.
