Product Description

The Eibach 0500.225.0700 ERS main coilover spring is engineered for performance suspension tuning where precise spring rate and durability are required. With a firm 700 lbs/in rate, this spring offers strong support and handling balance in a range of coilover suspension assemblies. Its 5 in free length and 2.25 in inside diameter make it suited for many custom coilover builds that require a compact yet capable spring for both street and track use.

Constructed from high-strength spring steel and finished in Eibach's signature red powder coat, the 0500.225.0700 spring is individually tested to ensure tight rate tolerances and predictable performance. It provides substantial travel and a compact block height, helping maximize suspension responsiveness while maintaining a robust load-bearing design. As a universal component, verify compatibility with your shock absorber and coilover hardware before installation.
