Spring 12in Coil-Over 3.75in ID Silver

The Spring 12in Coil-Over 3.75in ID Silver from EIBACH is a precision-engineered suspension component designed for automotive enthusiasts and fabricators who demand adjustable ride height and dampening control. This coil-over spring serves as the foundation for custom suspension setups on street cars, track vehicles, and modified platforms where factory geometry no longer suits performance or aesthetic goals.

The 12-inch length paired with a 3.75-inch inner diameter provides optimal packaging for coil-over conversion kits and custom suspension builds. EIBACH's coil-over springs are manufactured from high-tensile spring steel and precisely wound to maintain consistent rate and preload characteristics across the full range of suspension travel. The silver powder-coat finish protects against corrosion while resisting heat degradation common in performance applications, ensuring longevity whether the spring resides in engine bay environments or lower control arm mounting points.

This EIBACH coil-over spring benefits mechanics and automotive enthusiasts looking for a reliable solution for their suspension needs. Whether you're building a lowered daily driver, a competition-focused track car, or a show vehicle with custom chassis work, this spring delivers the tunability and reliability expected from one of the industry's most respected spring manufacturers.
