Spring 6in Coil-Over 3.0in ID Silver

The Spring 6in Coil-Over 3.0in ID Silver from EIBACH is a precision suspension component designed for enthusiasts and fabricators building custom lowered or performance-oriented vehicles. This coil-over spring serves as the elastic foundation of any performance suspension system, working in tandem with a damper to manage vehicle weight transfer, ride height, and cornering dynamics. Whether you're setting up a track-focused build, a street performance car, or a show-quality lowered platform, this EIBACH spring delivers the consistent spring rate and durability required for repeatable handling and predictable chassis behavior.

This coil-over features a 6-inch overall length and a 3.0-inch inner diameter (ID), making it compatible with standard coil-over kits and custom suspension platforms that accept this bore specification. EIBACH's silver finish resists corrosion and provides a clean, finished appearance visible through aftermarket wheels or custom suspension bays. The spring's engineering prioritizes consistent load support and minimal fade under sustained driving or track sessions, critical factors when managing the repeated compressions and extensions encountered during aggressive cornering, braking events, or extended performance driving. At 3.11 pounds, the spring's weight remains manageable for installation while maintaining the structural integrity necessary to support vehicle dynamics safely.

This spring is ideal for mechanics, suspension shops, and dedicated car builders integrating coil-over systems into sports cars, drift platforms, or road-racing vehicles where suspension tuning is essential. Verify your coil-over damper's inner diameter and overall spring length before purchase to ensure proper fitment—mismatched spring rates or bore sizes will compromise suspension geometry and handling. Installation typically requires proper spring compressors and fixture work; professional installation is recommended if you lack specialized suspension tools, as improper setup can affect vehicle safety and alignment.
