GSC Exhaust Valve Set – STD Size 33.50mm – Nissan TB48DE (Set of 12) – GSC2081-12
The GSC Power Division Standard Exhaust Valve Set (PN GSC2081-12) is precision-engineered for Nissan TB48DE engines requiring reliable sealing, high-temperature endurance, and optimized airflow. With a and a robust, these valves are built to perform under demanding conditions.
- 7mm
- 98.30mm
- 33.50mm
Developed using advanced 3D simulation and design tools, GSC’s exhaust valves feature a high-flow head profile tested specifically in TB48DE applications. The result: reduced face distortion, improved sealing under heat and pressure, and consistent performance throughout the valve’s lifespan.
- Promote smoother exhaust flow across the valve surface
- Reduces valve mass for better RPM response and boost tolerance
- Minimize oil retention and reduce drag for smoother movement
- Material: Modified 23-8n stainless steel for exhaust valves (heat-resistant and durable)
- Hardened or fused with stelite wafer for extended wear resistance
- Reduces tipping and simplifies valve lash setup
- Balances spring pressure to reduce shim use and enhance spring/retainer performance
- Compatibility: Works with OEM or GSC upgraded keeper/lock (new locks recommended for performance builds)
