GSC Conical Valve Spring Kit with Retainers (EZ36)

Valve spring performance is critical to engine durability, RPM capability, and valvetrain control. GSC Power-Division spring kits are engineered to provide the stability required for aggressive cam profiles, elevated boost levels, extended RPM ranges, and demanding racing environments.

Our spring systems are developed with careful attention to harmonics, installed loads, open pressures, coil dynamics, retainer compatibility, and long-term durability. Many GSC applications utilize advanced conical spring technology to improve damping characteristics, reduce harmonics, minimize spring stress, and maintain superior valve control at elevated engine speeds. The result is increased confidence when pushing horsepower, RPM, and boost beyond conventional limits.
