Eibach Valve Springs

Now, using the very same Eibach technology used in the IRL, Circle Track, Grand Am, and Speed World Challenge, you can get your engine performing at its very best. Eibach EVS Pro valve springs are precision-engineered and made from the highest quality material, eliminating the need for a dampening inner spring. The results: less weight and more performance.

Eibach EVS Pro valve springs feature:

* Race-proven motorsport quality
* Maximum lift for maximum performance and durability
* Increased seat pressure for optimum performance
* Higher natural frequency for high-rpm capability
* Dual chamfering for less wear on seats and retainers
* In-house SpinTron and Bosch dynamic testing
* Automated production for consistent quality
* Easy installation with stock retainers--no machining required
