    The ACT 600585 XACT Prolite flywheel is ACT's lightest, lowest-inertia flywheel offering, engineered for the sharpest throttle response and quickest acceleration across GM's shared LS-platform lineup. Materials are properly distributed for maximum strength, lower rotating inertia, good heat tolerance, and rigidity. Expect dramatically improved engine response and acceleration with mild-to-moderate gear rattle, a trade-off typical of a Prolite-class flywheel. It is forged, CNC-machined, and dynamically computer-balanced for smooth high-RPM reliability and is recommended for race use.

    FAQ

    Is the XACT Prolite flywheel good for daily driving?

    It can be driven on the street, but as ACT's lightest, lowest-inertia flywheel it is optimized for race use and carries mild-to-moderate gear rattle and somewhat reduced low-speed drivability compared to a heavier flywheel.

    What vehicles share this flywheel application?

    The 600585 covers GM's shared LS-platform driveline used in the Chevrolet Camaro (Z28, SS), Corvette (Z06, Grand Sport, 427, Base), SSR, Pontiac Firebird (Formula, Trans Am), GTO, and Cadillac CTS-V. See the full Vehicle Applications list above to confirm the exact year and trim.

    Can this flywheel be resurfaced?

    Yes, XACT flywheels are fully serviceable and can typically be resurfaced; confirm the resurfacing limit for this part before machining.

    Does this flywheel come with a clutch kit?

    No, the 600585 is a flywheel only. A separate ACT clutch kit (disc and pressure plate) is required to complete the driveline.
