GSC Conical Valve Spring Kit w/ Titanium Retainers – Subaru FA24F WRX (GSC5021)
Engineered for High RPM and Boost
The GSC Power-Division Conical Valve Spring Kit is designed specifically for the FA24F engine found in the 2022+ Subaru WRX. This complete kit includes 16 conical valve springs, 16 titanium retainers, and 16 precision spring seats—everything needed to stabilize your valvetrain under extreme conditions.
Why Conical Springs?
Conical springs outperform traditional cylindrical and beehive designs by naturally dampening valvetrain harmonics. Their progressive coil spacing and diameter variation absorb shock and reduce stress, extending the life of your engine components while supporting aggressive cam profiles and elevated RPMs.
Advanced Surface & Heat Treatment
Each spring undergoes a super-finished surface process and a proprietary multi-step heat treatment to ensure maximum durability and consistent performance. This kit is built for engines pushing the limits—whether you're chasing high boost or spinning past 10,000 RPM.
