Coilover Spring 3.0in ID 12in Tall 125lb

The Coilover Spring 3.0in ID 12in Tall 125lb from DRACO RACING is a precision-engineered suspension component designed for builders, racers, and enthusiasts who demand repeatable performance and reliable spring rates in coil-over applications. This single-unit spring provides the consistent load support necessary for custom suspension setups where tuning ride height and spring stiffness are critical to handling balance and ride quality. Whether you're assembling a road-racing platform, off-road competition vehicle, or street performance build, this coil spring delivers the linear force characteristics required for predictable suspension geometry.

Engineered with a 3.0-inch inner diameter and 12-inch overall height, this coilover spring accommodates most standard coil-over shock absorber bodies while maintaining compatibility with common suspension travel ranges. The 125 pounds-per-inch spring rate ensures moderate resistance to compression, ideal for applications requiring a balance between ride comfort and body control—neither too soft for high-lateral-load situations nor so stiff as to compromise ride quality on uneven surfaces. Constructed from high-grade steel and finished with a durable purple powder coat, the spring resists corrosion and UV degradation while providing visual identification in multi-spring setups. The 3.2-pound weight is consistent with steel coil springs of this specification and dimension.

Professional suspension technicians and DIY builders alike benefit from DRACO RACING's attention to spring rate accuracy and dimensional consistency—critical factors when fine-tuning corner weights and ride frequency for autocross, road racing, or off-road duty. When installing this component, verify that your coil-over shock body accepts a 3.0-inch ID spring and that 12-inch compressed height fits your vehicle's target ride height and suspension geometry. Pair this spring with matched units at all four corners for balanced suspension dynamics, and always consult your vehicle's suspension design specifications to confirm compatibility with your chosen shock platform and mounting configuration.
