Spring 18in Coil-Over 3.0in ID Silver

The Spring 18in Coil-Over 3.0in ID Silver by EIBACH is a premium suspension component engineered for drivers and tuners who demand precise ride height adjustment and enhanced handling dynamics. Whether you're building a street machine, track-focused platform, or daily driver with aggressive lowering goals, this 18-inch coil-over spring provides the foundation for controlled suspension tuning. EIBACH's reputation in the aftermarket suspension industry stems from decades of racing heritage, and this component reflects that commitment to performance and reliability in a compact, silver-finished package.

The 3.0-inch inside diameter (ID) specification ensures compatibility with standard coil-over shock bodies and suspension kits across multiple vehicle platforms and tuning applications. The 18-inch length allows for fine-tuned ride height adjustment, critical when dialing in corner weights, anti-roll bar stiffness, and overall weight distribution for optimal performance. EIBACH springs are manufactured to tight tolerances with consistent spring rates, eliminating the variance common in lower-tier alternatives and ensuring predictable suspension behavior under acceleration, braking, and cornering loads. The silver finish resists corrosion and provides a clean aesthetic appearance visible through wheel wells on lowered vehicles.

This coil-over spring is ideal for enthusiasts pairing it with adjustable shock absorbers in custom suspension builds, kit installations, or replacement scenarios where OEM springs no longer meet performance objectives. Installation typically requires removing wheels, unloading the suspension, and compressing or removing the existing spring before positioning the new 18-inch EIBACH unit onto the shock body. Always verify your specific vehicle platform and shock compatibility before purchase, as 3.0-inch ID springs work with universal-style coil-over kits and many performance shock manufacturers' designs. Professional installation is recommended to ensure proper spring seating, correct ride height geometry, and safe operation of your suspension system.
