EVS | Eibach Valve Springs
- Single spring design for reduced mass, lower friction and less heat
- Maximum lift for maximum performance and durability
- Increased seat pressure for optimum performance
- Higher natural frequency for high RPM capability
- Dual chamfering for lower wear on seats and retainers
- Easy installation with stock retainers – no machining required
Now, using the very same Eibach technology used in IRL, Grand Am, and Speed World Challenge, you can get your engine performing at its very best.
Eibach EVS-Sport valve springs are precision engineered and made from highest quality material—eliminating the need for a dampening inner spring.
The result: less weight and more performance.
