Spring Coilover 8.0in 3.0in ID 400 Rate

The DRACO RACING Spring Coilover 8.0in 3.0in ID 400 Rate is a precision-engineered coil spring built for high-performance suspension tuning in off-road vehicles, competition trucks, and platform-based recovery rigs. This 8-inch length, 400 lb/in spring rate unit delivers the stiffness needed to manage heavy payloads, aggressive terrain, and dynamic load shifts without bottoming under extreme compression. The 3-inch inner diameter and steel construction with purple powder coat finish provide both structural integrity and visual distinctiveness for serious suspension builders.

At 3.34 lbs per unit, the coilover spring is engineered for coil-over shock applications where spring rate consistency is critical to suspension geometry and vehicle control. The 400 lb/in rate sits in the moderate-to-stiff range, suitable for lifted trucks carrying auxiliary equipment or for off-road platforms requiring reduced ride height without sacrificing load capacity. The steel construction resists fatigue from cyclic loading over extended service life, while the purple powder coating provides corrosion resistance in salt-heavy environments and humid climates where suspension components face accelerated wear.

This coilover spring is specified by platform builders and recovery specialists who demand repeatable suspension performance and precise load handling. Whether supporting off-road patrol vehicles, tactical transport, or expedition-grade recovery trucks, the 400 lb/in rate delivers the midrange firmness needed for mixed terrain without requiring the extremely heavy rates reserved for maximum-capacity platforms. Customers sourcing complete coilover kits or upgrading individual spring elements will find this DRACO RACING component compatible with standard 3-inch ID shock absorber designs across leading suspension manufacturers.
