The ACT XACT Prolite flywheel for 1977 Chevrolet K5 Blazer is ACT’s lightest offering, optimized for lowest inertia to improve throttle response and acceleration. Intended for road or rally racing, the Prolite sacrifices some drivability for faster engine response. Materials are distributed for strength, heat tolerance and rigidity; the flywheel is serviceable and can be resurfaced.
