Spring 12in Coil-Over 2.5in ID

The Spring 12in Coil-Over 2.5in ID by Eibach is a premium coil-over spring designed for drivers and tuners who demand precise suspension geometry and consistent ride control. Built for custom suspension builds, lowering kits, and performance chassis setups, this spring delivers the linear spring rate characteristics that separate professional-grade components from entry-level parts. Whether you're building a track-focused platform or dialing in a street suspension, Eibach's engineering ensures repeatable performance across a wide temperature and load range.

This 12-inch coil-over spring features a 2.5-inch inner diameter, which directly determines compatibility with standard coil-over damper shafts and allows for seamless integration into most aftermarket suspension systems. Eibach springs are manufactured using high-grade spring steel and precision-wound to maintain consistent load characteristics throughout the suspension travel range. The 12-inch compressed length makes this spring ideal for applications requiring moderate ride height adjustment while preserving adequate suspension travel for bump absorption and compliance—critical factors when balancing aggressive stance with drivability.

Mechanics and suspension specialists rely on Eibach components for builds requiring OEM-level quality with performance tuning capabilities. The 2.5-inch ID diameter is standard across most modern coil-over platforms, making this spring compatible with a broad range of aftermarket dampers. With its robust design and precise engineering, this coil-over spring is an excellent choice for enhancing vehicle performance.
