GSC Power Division Exhaust Valve – +1MM Super Alloy, Single for Gen 3 Coyote 5.0L - GSC2167-01
Designed for 2018–2023 Ford Mustang GT models with the Gen 3 5.0L Coyote engine, this single +1MM oversized exhaust valve from GSC Power Division is built from high-temp super alloy for extreme durability in turbocharged and high-RPM applications.
Unlike the OEM design, GSC’s valve features a 45° seat contact angle (vs. the factory 40°), which requires a valve job to ensure proper sealing and valvetrain geometry. Using advanced 3D modeling and simulation, GSC engineers a high-flow valve head that’s tested in real-world conditions for maximum performance. The result is reduced face distortion, improved sealing under pressure, and consistent output over time.
Key Features:
- Improved Airflow: Optimized valve head design enhances engine breathing and power
- Back-Cut Profile: Reduces valve weight to support higher RPM operation
- Micro-Polished Stem: Minimizes oil retention and drag for smoother guide movement
- Super Alloy Build: Engineered to withstand extreme heat and turbocharged stress
- Stellite-Tipped Ends: Hardened or fused tips resist wear and maintain geometry near the rocker or tappet
- OEM-Compatible Locks: Works with factory keeper systems; new locks recommended for performance builds
- Built for Reliability: Backed by GSC’s reputation for precision and long-term durability
