Spring 12in Coil-Over 2.50in ID Silver

The Spring 12in Coil-Over 2.50in ID Silver from Eibach represents a cornerstone component in performance suspension tuning, designed for enthusiasts and professionals who demand precise ride height control and optimized spring rate matching. This 12-inch coil-over spring is engineered to work in tandem with adjustable coil-over suspension systems, allowing you to dial in both compression and rebound characteristics for street, autocross, or track applications. Whether you're building a dedicated performance platform or fine-tuning an existing setup, this Eibach spring delivers the engineering heritage that has made the brand synonymous with suspension excellence across motorsports.

The 2.50-inch inner diameter (ID) specification ensures compatibility with industry-standard coil-over shock bodies, while the 12-inch length provides the ride height adjustment range critical for lowered platforms without sacrificing suspension travel or introducing binding issues. Eibach's proprietary spring technology focuses on consistent rate linearity and minimal spring bind, meaning you'll experience predictable handling response across varied load conditions—essential when you're pushing limits on the track or managing weight transfer during aggressive cornering. The silver finish provides both corrosion resistance and visual appeal, maintaining aesthetics in engine bays or exposed suspension setups. At 3.52 lbs per spring, the lightweight construction reduces unsprung mass, directly improving suspension responsiveness and ride quality.

This coil-over spring is ideal for builders working with adjustable coil-over kits on performance-oriented platforms—from street-tuned daily drivers to serious track cars requiring precise setup flexibility. Installation pairs seamlessly with compatible shock absorbers featuring 2.50-inch bores, and the 12-inch length supports both lowered and raised ride height configurations depending on your suspension geometry and spring rate selection. Verify your shock body bore diameter and available suspension travel before purchase to ensure optimal fitment and prevent coil bind or inadequate bump stop clearance. For mechanics and enthusiasts seeking repeatable, tunable suspension performance without compromise, Eibach's coil-over spring delivers both engineering credibility and real-world adjustability.
