Precision Valve Train Stability for Subaru FA20

The GSC Power Division Dual Cylindrical Valve Spring Kit is the ultimate solution for Subaru FA20 engine owners looking to increase their RPM range and boost reliability. Engineered for the WRX, BRZ, and FRS platforms, this kit addresses the common limitations of the factory valve train under high-performance conditions.

Why Choose GSC Dual Springs?

• Dual Spring Design: Provides increased seat pressure and harmonic control compared to single-spring setups.
• Cylindrical Geometry: Optimized for consistent tension throughout the entire valve lift cycle.
• Durability: Manufactured from high-grade materials to resist fatigue and heat soak.
• Platform Specific: Engineered specifically for the FA20 engine architecture.

When running aftermarket camshafts or increased boost, the stock valve springs are often insufficient, leading to valve float and potential engine damage. This GSC kit ensures your valves close precisely at high RPM, allowing you to safely push your Subaru further. Whether you are building for the track or the street, the peace of mind provided by a robust valve train is invaluable. These springs are designed to handle the rigors of high-performance driving while maintaining OEM-like reliability.
