Description
Valve spring performance directly impacts your engine’s ability to maintain valve control at high RPM, preventing float and ensuring consistent combustion. This dual spring kit with damper delivers the stiffness and stability needed for aggressive cam profiles and forced induction applications. Whether you’re building a street-strip hybrid or a dedicated race engine, reliable valve actuation is non-negotiable.
The 348 lb/in rate strikes the balance between maintaining aggressive lift and resisting spring surge, while the integral damper controls harmonics that can lead to premature failure. CNC-precision steel components ensure repeatable performance across heat cycles and extended use.
