Scion FR-S Valve Spring Kit - GSC Power Division - Single Beehive Titanium Retainers/Chromoly Seats - `13-`15. This GSC Power Division kit replaces the factory valve springs with single beehive springs paired with lightweight titanium retainers and durable chromoly seats for 2013–2015 Scion FR-S / Subaru BRZ FA20 applications.

Designed for enthusiasts upgrading cams or pushing higher RPM safely, the single beehive spring shape reduces mass at the retainer end while maintaining stable coil support near the seat. Titanium retainers cut valvetrain weight to improve control and reduce inertia, while chromoly seats increase durability where spring and retainer meet. The kit is intended to work with FA20 valve geometry and retains a compact profile suitable for many performance valvetrain builds. It is a practical choice for owners seeking reliable valve control without changing guides or other major components.
