Coilover Spring 7in x 2.5in x 750lb Barrel

The SWIFT SPRINGS Coilover Spring 7in x 2.5in x 750lb Barrel (Model 070-250-700 B) is a precision coil spring engineered for suspension systems requiring consistent, reliable load support and controlled deflection. This coil-over barrel spring delivers a 750 lb/in spring rate, making it suitable for applications where predictable spring action and durability under cyclic loading are critical operational requirements. The robust steel construction with black powder coat finish provides corrosion resistance and extended service life in demanding environments.

The 7-inch length and 2.5-inch inner diameter (ID) configuration conform to standard coil-over mounting specifications, enabling direct integration into compatible suspension assemblies. The 750 lb/in spring rate determines the amount of force required to compress the spring one inch—a critical specification for tuning suspension response, controlling body roll, and maintaining ride height under load. The black powder coat finish protects the steel substrate from rust and corrosion, essential for springs exposed to moisture, salt air, or harsh weather conditions. At 4.42 lbs per unit, the spring's weight is optimized for performance applications where unsprung mass reduction directly impacts handling dynamics.

This coil spring serves motorsports, off-road vehicle builds, suspension upgrades, and performance tuning projects. Engineers and suspension specialists select springs by rate and geometry to achieve specific handling characteristics—stiffer rates reduce suspension compliance for firmer response, while accommodating heavier payloads or competitive driving demands. SWIFT SPRINGS coil-over barrels are widely specified in street performance, track applications, and lift kit assemblies where spring rate consistency and longevity determine overall suspension reliability and predictability.
