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.
