The ACT XACT Prolite flywheel for 1977 Chevrolet K5 Blazer is a lightweight, low-inertia choice aimed at improved throttle response and quicker acceleration. Prolite flywheels are preferred in road or rally settings where rapid engine response matters, though they may reduce everyday drivability. Materials are distributed for strength, heat tolerance and rigidity, and the unit is serviceable and resurfaceable.
