Spring 14in Coil-Over 2.5in ID

The Spring 14in Coil-Over 2.5in ID by EIBACH is a precision suspension component engineered for builders and mechanics seeking refined ride control and lowered stance on their vehicles. This coil-over spring serves as the load-bearing element in modern adjustable suspension setups, allowing independent tuning of ride height and spring rate without replacing entire strut assemblies. Whether you're building a street machine, optimizing track geometry, or dialing in a show car, this 14-inch spring delivers the adjustability serious enthusiasts demand for customized suspension geometry and improved handling dynamics.

Built to EIBACH's exacting standards, this coil-over spring features a 2.5-inch inner diameter that interfaces with standard coil-over shock bodies and strut housings found across high-performance platforms. The 14-inch length is designed for mid-travel suspension architectures, offering adequate compression and extension ranges for both street and circuit applications. EIBACH's proprietary spring steel and heat-treatment process ensure consistent rate linearity, minimal hysteresis, and durability through thousands of compression cycles—critical when running aggressive lowering or handling aggressive cornering loads that demand stable, predictable suspension response.

This spring pairs seamlessly with aftermarket coil-over kits from major suspension manufacturers and fits most universal coil-over platforms used in drift, road racing, and street applications. Mechanics and fabricators often specify EIBACH springs when rebuilding tired suspension systems or upgrading OEM dampers to adjustable coil-over technology, as the proven rate curves and build quality reduce setup time and tuning iterations. Installation requires basic suspension knowledge and proper spring compression tools; verify inner diameter compatibility with your shock body before purchase to ensure proper seating and optimal damper performance across the vehicle's load range.
