Product Description

The Eibach 0800.250.1000 ERS main coilover spring is engineered for high-performance suspension systems where a strong spring rate and precise behavior are essential. With a **1000 lbs per inch** spring rate, **8.00 in free length**, and **2.50 in inside diameter**, this spring delivers firm support and predictable handling characteristics - making it ideal for performance street cars, track-focused builds, and motorsport applications.

Constructed from high-tensile spring steel with a durable red powder-coat finish, the 0800.250.1000 provides generous travel paired with an optimized block height to maintain suspension responsiveness and stability under dynamic conditions. Each spring is individually tested to ensure consistent performance and rate accuracy typical of Eibach's ERS line. Because this part is universal - not tied to a specific vehicle - verify compatibility with your coilover shocks and hardware before installation for the best results.
