ACT 601016 XACT Prolite Performance Racing Flywheel

The ACT 601016 XACT Prolite flywheel is a high-performance, lightweight racing flywheel engineered to deliver dramatically improved engine response and acceleration for competition vehicles. Designed specifically for road racing and rally applications, this flywheel prioritizes maximum throttle response over street drivability.

Key Performance Features:

• Lightweight prolite design with lowest moment of inertia for fastest throttle response and acceleration
• One-piece forged construction eliminates failure points and provides uniform, efficient heat transfer from the clutch disc
• Heat-treated forging ensures exceptional strength and toughness under extreme racing conditions
• Induction-hardened ring gear delivers maximum durability and extended service life
• CNC machined and dynamically computer balanced for smooth, reliable high-RPM operation
• Optimized material distribution for maximum strength, rigidity, and heat tolerance
• Fully serviceable and resurfaceable—no additional parts required for maintenance

Important Considerations:

This flywheel is recommended for race use and may produce mild to moderate gear rattle. The reduced rotational mass provides race-level performance but results in reduced street drivability compared to heavier flywheels. The one-piece construction eliminates common failure modes like warped inserts or loose ring gears found in multi-piece designs.
