GSC Intake Valve Set – Stainless Steel STD Head – Nissan RB26DETT (Set of 12) – GSC2142-12
The GSC Power Division Stainless Steel Intake Valve Set (PN GSC2142-12) is precision-engineered for Nissan RB26DETT engines demanding consistent airflow, thermal stability, and long-term durability. Featuring a standard 34.6mm head diameter and a finely machined 5.967mm stem, these valves are optimized for high-RPM operation and aggressive cam profiles.
- Head Diameter: 34.6mm / 1.362in
- Total Length: 102.4mm / 4.031in
- Stem Diameter: 5.967mm / 0.235in
Designed using advanced 3D modeling and simulation tools, GSC’s intake valves feature a high-flow head profile tested specifically in RB26DETT platforms. The result: reduced face distortion, improved sealing under extreme heat, and consistent performance throughout the valve’s lifespan.
- Enhance airflow and improve combustion efficiency
- Reduces valve mass for better RPM response and boost tolerance
- Minimize oil retention and reduce drag for smoother valve movement
- Material: Modified 21-4n stainless steel for intake valves—built for high heat and long-term durability
- 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 keeper/lock systems or GSC upgraded options (new locks recommended for performance builds)
Backed by GSC Power Division’s reputation for precision, durability, and performance in sport compact valvetrain components.
