GSC P-D Mitsubishi Evo 4-9 4G63 Race Balance Shaft

This GSC P-D Race Balance Shaft replaces the factory primary drive unit in 4G63 engines powering Mitsubishi Lancer Evolution 4-9 DSM Eclipse Talon and Galant VR-4 models. Machined from billet 4340 steel it weighs only 1.6 lbs compared to OEM 4 lbs delivering faster engine response higher rev limits and less rotational mass. Perfect for drag road race and time attack builds needing smoother operation at peak RPMs.

Key Features

• Billet 4340 Steel Construction: Delivers maximum strength and fatigue resistance for extreme race conditions in high horsepower 4G63 setups.
• 60% Weight Reduction: Cuts mass from OEM 4 lbs to 1.6 lbs accelerating revving reducing parasitic drag and improving throttle response.
• Reduced Bearing Surface: 0.866 inch diameter versus OEM 1.100 inch minimizes oil drag enabling freer spinning at high RPMs.
• Direct OEM Replacement: Bolts directly into factory housing using stock gears and mounting points with zero modifications required.
