SuperSprings SuperCoils Heavy-Duty Replacement Coil Springs

SuperSprings SuperCoils are heavy-duty direct replacement coil springs engineered to solve suspension sag at its source — not just mask the symptoms. While spacer kits may raise a vehicle temporarily, they do nothing to address a worn or overloaded spring. SuperCoils fully replace the factory coil spring itself, restoring proper suspension geometry, ride height, and load-carrying capacity for a long-term, dependable solution.

Factory coil springs lose their load-carrying ability over time through repeated compression cycles, age, and the added strain of specialty equipment such as snow plows, heavy bumpers, winches, and armor plating. SuperCoils address this at the source by substituting the spring with a superior heavy-duty unit, delivering a higher spring rate, restored ride height, and predictable handling whether the vehicle is loaded or empty.

Key Features:

• True direct OEM replacement — fully replaces factory coil springs rather than supplementing them
• Premium shot-peened steel construction for superior strength and long-term fatigue resistance
• Linear, constant spring rate consistent with factory coil spring design for predictable, stable handling
• Corrosion-resistant powder coat finish protects against road salts, mud, and harsh environments
• Maintenance-free design — no air lines, compressors, or periodic adjustments required
• Available for front and rear applications across a wide range of trucks and vans
• Rigorously tested for consistent performance through repeated compression and rebound cycles
• Backed by the SuperSprings limited warranty

SuperCoils vs. Spacer Kits

Spacer kits may raise a vehicle, but the weak stock coil still carries all the load — meaning sag, harsh bottom-outs, and a compromised ride will return over time. SuperCoils solve the problem at its root by replacing the spring itself, with no added stress on surrounding suspension components and no ongoing maintenance requirements.

Trusted by fleets, commercial upfitters, and everyday drivers who demand long-term suspension strength for towing, hauling, and demanding work conditions, SuperCoils deliver a reliable fit-it-and-forget-it suspension upgrade. Select the correct part number for your specific vehicle application to ensure proper fitment.
