Eibach ERS 2.5in ID Helper Springs HELPER250M - Universal Coilover Fit
Eibach ERS 2.5in ID Helper Springs (HELPER250M) deliver progressive support to main coilover springs, preventing full compression and maintaining tire contact patch during aggressive cornering or low ride heights. These polyurethane rubber helpers fit universally on coilover kits with 2.5-inch inner diameter struts and perches, compatible across numerous performance vehicles. Sold as a pair, they enhance suspension response and durability for street or track use.

- 70mm Free Height: 2.76in (70mm) length ensures full engagement at ride height while allowing full droop without binding.
- High-Density Polyurethane: Tough rubber compound resists heat, ozone, and chemicals for long-lasting performance in demanding conditions.
