GSC Power-Division Subaru FA20 Dual Cylindrical Valve Spring Kit for WRX, BRZ, and FR-S
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2012-2021 Subaru BRZ and WRX, Scion FR-S, and Toyota 86 models equipped with the FA20 or FA20DIT engine.
The GSC Power-Division Dual Cylindrical Valve Spring Kit is engineered for high-performance Subaru FA20 engines that require superior valve control at elevated RPM levels. By utilizing a dual-spring design, this kit provides the necessary seat pressure and spring rate to prevent valve float, which is critical when running increased boost pressures or aggressive aftermarket camshaft profiles.
This kit is manufactured using premium-grade valve spring wire to ensure long-term durability and resistance to fatigue. The dual cylindrical configuration provides enhanced harmonic damping compared to single-spring setups, ensuring stable valvetrain operation throughout the powerband.
- Engineered specifically for the Subaru FA20 engine architecture
- Dual cylindrical spring design for maximum valvetrain stability
- Higher seat pressure to prevent valve float at high RPM
- Compatible with both naturally aspirated and turbocharged FA20 variants
- Precision-manufactured for consistent spring rates and tolerances
