ACT 600455 XACT Flywheel Prolite Disc for GM

600455 is a Prolite flywheel, which is ACT's lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Features

• Improved engine response and acceleration with lightweight design
• ACT heat treats the entire forging for strength and toughness, and induction hardens our ring gears for longest gear life
• One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No more warped inserts or loose ring gears
• Recommended for high horsepower street or race use
• All flywheels are CNC machined and dynamically computer balanced for super smooth high RPM reliability
