The ACT 600585 XACT Prolite flywheel is ACT's lightest flywheel offering with the lowest rotational inertia, designed for the sharpest throttle response and quickest acceleration across GM's LS-series Camaro, Corvette, Cadillac CTS-V, Firebird, GTO, and SSR applications. Prolite flywheels are preferred for road racing or rally racing and carry somewhat reduced low-speed drivability versus a heavier stock flywheel. Material is properly distributed for maximum strength, good heat tolerance, and rigidity. The flywheel is forged, CNC-machined, and dynamically computer balanced for smooth high-RPM reliability, and one-piece construction eliminates warped inserts or loose ring gears. It is fully serviceable and can be resurfaced with no additional parts required.
