Coilover Spring 3.0in ID 12in Tall 300lb

The DRACO RACING Coilover Spring 3.0in ID 12in Tall 300lb is a precision-engineered coil-over suspension spring designed for high-performance off-road vehicles and custom suspension builds. Manufactured from steel with a purple powder coat finish, this spring delivers consistent spring rate performance across its full range of motion, making it an essential component for builders seeking reliable, tuned suspension geometry.

With a 300 lb/in spring rate and 12-inch compressed length, this coilover spring is engineered for specific load and travel requirements common in performance suspension systems. The 3.0-inch inner diameter accommodates standard coilover body diameters, ensuring straightforward integration into compatible suspension platforms. The purple powder coat provides corrosion resistance and visual identification during assembly and maintenance. At 5.05 lbs per spring, weight is a key consideration in suspension tuning, particularly for applications where unsprung mass reduction impacts handling dynamics and ride quality.

This spring is specified for custom off-road suspension builds, race vehicle setups, and performance coilover installations where precise spring rates are critical to achieving desired ride height, load support, and suspension travel. Buyers integrating coilover springs must verify compatibility with their specific coilover bodies, mounting perches, and suspension geometry to ensure proper fitment and performance. Individual springs are sold as single units, so matched sets require ordering multiple springs as needed for your suspension configuration.

Performance suspension systems rely on matched spring rates to maintain vehicle balance and handling characteristics. The 300 lb/in rate positions this spring within the mid-range stiffness spectrum typical of off-road coilover applications, where adequate load capacity must balance comfort and responsiveness. Proper suspension setup requires attention to spring preload, height adjustment, and damper tuning to achieve the intended performance envelope.
