GSC Intake Valve – Extended Tip Stainless Steel STD – Nissan RB26DETT Single (GSC2146-01)
The GSC Power Division Extended Tip Stainless Steel Intake Valve (PN GSC2146-01) is designed for Nissan RB26DETT engines requiring precise valve train geometry and enhanced durability. Featuring a standard 34.6mm head diameter and extended 103.85mm total length, this valve is ideal for high-performance builds demanding consistent sealing and optimized lash adjustment.
- Head Diameter: 34.6mm / 1.362in
- Total Length: 103.85mm / 4.089in
- Stem Diameter: 5.967mm / 0.235in
Developed using advanced 3D modeling and simulation software, GSC’s intake valves feature a high-flow head profile tested specifically in RB26DETT platforms. The extended tip design helps maintain proper valve train geometry while reducing tipping. Less face distortion under heat means better sealing and more reliable performance over time.
- Promote smoother airflow and improved combustion efficiency
- Reduces valve mass to support higher RPM operation
- Minimize oil retention and reduce drag for smoother movement within the guide
- Material: Made from modified 21-4n stainless steel for strength and heat resistance
- Hardened or fused with stelite wafer for extended wear and durability
- Tailored for specific setups to simplify valve lash adjustment and maintain geometry
- Balances spring pressure and reduces need for shims, enhancing spring/retainer performance
- Compatibility: Works with OEM keeper/lock systems; new locks recommended for performance builds
Backed by GSC Power Division’s commitment to precision, durability, and high-performance engineering.
