Spring 6in Coil-Over 3.0in ID Silver

The Spring 6in Coil-Over 3.0in ID Silver from EIBACH is a precision-engineered suspension component designed for performance vehicles and custom builds requiring tunable ride height and spring rate control. Coil-over springs are essential for builders and enthusiasts who need independent adjustment of damping and spring preload, enabling fine-tuned handling characteristics across varying load conditions and driving applications. Whether you're upgrading a track-focused platform or building a custom street suspension, this silver-finished coil-over spring delivers the adjustability and reliability demanded by serious builders.

This 6-inch coil-over spring features a 3.0-inch inner diameter bore specification, engineered to work seamlessly with standard coil-over shock assemblies and damper housings. The silver finish provides corrosion resistance and a professional appearance while maintaining structural integrity under dynamic suspension loads. EIBACH's manufacturing precision ensures consistent spring rate performance and minimal variance unit-to-unit, critical factors when paired with adjustable dampers for precise suspension geometry tuning. The compact dimensions (4.9 x 4.55 x 8.9 inches) and lightweight 3.11-pound construction make installation straightforward while minimizing unsprung weight in your suspension system.

Performance builders, motorsport competitors, and suspension technicians depend on this coil-over spring for applications requiring modular suspension architecture and ride-height adjustability. It pairs seamlessly with aftermarket coil-over kits and OEM-equivalent damper systems on sport compact cars, drift platforms, and road-racing vehicles. Proper installation requires matching this spring to the corresponding damper specifications and ensuring correct preload adjustment for your vehicle's intended use and weight distribution. Verify compatibility with your coil-over shock assembly's bore diameter and spring perch design before ordering.
