GSC Exhaust Valve – Standard Size for Mitsubishi 4G63T – GSC2001-01

The GSC2001-01 standard-size exhaust valve is engineered for Mitsubishi 4G63T applications, featuring a 30.5mm head diameter, 6.6mm stem, and 109.20mm overall length.

Developed using advanced 3D modeling and flow simulation, GSC’s valve head design delivers improved airflow and durability. Each prototype is flow-tested in its intended application to ensure maximum performance. The result: reduced face distortion, better sealing under extreme conditions, and consistent output over time.

Key Features:

  • Swirl-polished heads enhance airflow across the valve surface
  • Back-cut design reduces weight for higher RPM and boost, supporting aggressive cam profiles without increasing seat pressure
  • Micro-polished stems minimize oil retention and drag for smoother movement
  • Exhaust valves use modified 23-8N stainless for high heat tolerance and long-term reliability
  • Valve tips are hardened or fused with a stelite wafer, maintaining wear resistance within 5 Rockwell C of the rocker or tappet
  • Tip heights are optimized to reduce valve tipping and simplify lash adjustment during installation
  • Keeper grooves are precision-tuned to balance spring pressures and reduce the need for shims when paired with GSC spring and retainer kits
  • Compatible with OEM keepers/locks or GSC upgraded versions; reuse of old locks is not recommended for performance builds due to material wear
