GSC High Pressure Conical Valve Spring Kit w/ Titanium Retainers – Subaru FA24F WRX (GSC5024)
Built for Boost and RPM Extremes
The GSC Power-Division High Pressure Conical Valve Spring Kit is purpose-built for the FA24F engine in the 2022–2024 Subaru WRX. This complete kit includes 16 conical valve springs, 16 titanium retainers, and 16 precision spring seats—engineered to handle elevated boost and aggressive cam profiles with confidence.
Conical Design for Harmonic Control
Unlike traditional cylindrical or beehive springs, conical springs feature progressive coil spacing and diameter variation, acting as natural harmonic dampers. This design reduces valvetrain stress, minimizes wear, and enhances component longevity—especially critical in high-output turbocharged engines.
Advanced Surface & Heat Treatment
Each spring is treated with a super-finished surface process and a proprietary multi-step heat treatment to ensure consistent performance and durability. Whether you're chasing 10,000 RPM or 60 psi of boost, this kit is built to keep your valvetrain stable and responsive.
