GSC Power-Division Dual Conical Valve Spring Kit for Subaru EJ Series - 5074
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Designed specifically for the Subaru EJ series engine, the GSC Power-Division Dual Conical Valve Spring Kit (MPN 5074) provides the valvetrain stability required for high-performance and high-RPM builds. This kit addresses the inherent harmonic challenges of the EJ platform by utilizing a specialized dual conical geometry.
The dual conical design offers progressive damping characteristics that significantly reduce harmonic resonance compared to traditional cylindrical springs. This ensures more consistent seat pressure and prevents valve float, protecting your engine during aggressive cam profiles or high-boost applications. By minimizing top-end mass while maintaining superior control, these springs allow for a higher rev limit and improved valvetrain longevity.
- Fits all Subaru EJ series engines
- Dual conical spring geometry for superior harmonic damping
- Increased seat pressure to prevent valve float at high RPM
- Engineered for high-performance street and track applications
- Manufacturer Part Number: 5074
