600125 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. XACT Flywheel Prolite Dramatically improved engine response and acceleration, mild to moderate gear rattle; Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum 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 race use; Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT XACT ProLite Flywheel is a lightweight performance flywheel engineered to improve engine response, throttle response, and acceleration. Part number ACT600125 features ACT’s lowest-inertia ProLite design, making it well suited for road racing, rally racing, and other applications where rapid engine speed changes are a priority. Its reduced rotational mass helps the engine rev more quickly while maintaining the strength and heat tolerance required for demanding use.

Manufactured from a heat-treated forging, the ACT XACT ProLite Flywheel uses a one-piece construction that supports consistent heat transfer and reduces the risk of warped inserts or loose ring gears. The induction-hardened ring gear is designed for long service life, while CNC machining and dynamic computer balancing promote smooth operation at high engine speeds. This flywheel is serviceable and can be resurfaced when needed, helping extend its useful life without requiring additional replacement components. Because the lighter design may produce mild to moderate gear rattle and reduced street drivability, it is recommended primarily for race-focused applications.

Fitment: Designed for select 2002–2008 Honda Civic applications and the 2006 Acura RSX. Verify engine, transmission, and vehicle specifications before installation. The ACT600125 ProLite Flywheel is backed by ACT’s limited one-year warranty. Professional installation is recommended, and the flywheel should be installed with compatible clutch components according to the vehicle and manufacturer service procedures.

What's Included: One ACT XACT ProLite Flywheel with an integrated ring gear.

Note: This product is intended for automotive performance use. California emissions certification does not apply, and Proposition 65 warnings may apply.
