ACT 601325 XACT Pro-Mass Flywheel

The ACT 601325 XACT Pro-Mass Flywheel is engineered to deliver confidence-inspiring momentum for demanding applications including off-road crawling, towing, and vehicles with oversized tires. This one-piece forged flywheel eliminates the problematic dual-mass design, providing superior reliability without gear rattle or driveline slop.

Key Features:

• Heat-treated forging construction for exceptional strength and toughness
• Induction-hardened ring gear for maximum durability and service life
• One-piece design creates an efficient heat sink for the clutch system while eliminating failure points associated with dual-mass flywheels
• Pro-Mass design with optimized inertia distribution for improved climbing and pulling capabilities with minimal weight penalty
• CNC machined and dynamically computer balanced for smooth, vibration-free operation
• Resurfaceable design allows for extended service life without purchasing additional components
• Recommended for both street and off-road applications

The XACT Pro-Mass Flywheel provides the perfect balance between increased rotational mass for better low-end performance and weight efficiency, making it ideal for enthusiasts who demand both reliability and capability from their drivetrain.
