Developed using advanced 3D modeling and simulation, GSC’s oversized intake valve features a that’s been flow-tested in VR38-specific applications. The result: improved sealing at high temps, and consistent performance throughout the valve’s lifespan.
- Enhances airflow across the valve surface
- Reduces weight for improved RPM and boost response
- Minimizes oil retention and drag for smoother movement
- Material: Modified 21-4n stainless steel for intake valves (heat-resistant and durable)
- Hardened or fused with stelite wafer for extended wear resistance
- Reduces valve tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM keeper/lock or GSC upgraded options (new locks recommended for performance builds)
Whether you're chasing airflow gains or long-term reliability, this is built to meet the demands of high-performance VR38DETT setups.
