Spring Coilover 12in x 2.5in

The Eibach Spring Coilover 12in x 2.5in is a precision-engineered coil spring designed for automotive suspension tuning and performance vehicle builds. This individually-rated spring is purpose-built for coilover suspension systems, where tuning spring rates allows mechanics and enthusiasts to dial in exact ride height, stiffness, and handling characteristics. Whether you're building a track-focused platform or refining a street-driven daily driver, this component is essential for achieving the suspension geometry and damping response your build demands.

Manufactured from high-strength steel and finished in a durable silver powder coat, the Eibach Spring Coilover features a 275 lb/in spring rate with a 2.5-inch inner diameter and 12-inch length. This stiffness rating sits in the moderate-to-firm range, suitable for street performance applications where cornering grip and body control matter without sacrificing ride comfort entirely. The 4.25 x 4.25-inch coil diameter and consistent wire gauge ensure predictable load distribution, minimal oscillation, and years of consistent performance. Eibach's engineering reputation ensures this spring maintains rate linearity across its stroke, critical for predictable suspension behavior during aggressive driving.

This coilover spring works best in complete coilover assemblies paired with matched shock absorbers and appropriate spring perches. Buyers sourcing suspension components for lightweight platforms, drift builds, autocross cars, or road-racing applications will find this rate versatile across many chassis weights and power levels. Installation requires removal of the factory suspension and assembly into your chosen coilover system; professional installation is recommended to ensure proper ride height, alignment, and shock damping tuning. Verify compatibility with your coilover kit's bore size and spring seating specifications before purchase.
