Description This lightweight steel flywheel made by Bastuck weighs only 8.88 lbs (11.5 lbs with ring gear) while the stock flywheel with ring gear weighs approximately 20.5 lbs. Reducing the weight of the flywheel allows the engine to rev faster, increasing throttle response and acceleration. Includes clutch pressure plate bolts, dowel pins, and ARP flywheel bolts. Flywheel is supplied with the ring gear installed. Steel flywheels have a more reliable attachment to the crankshaft than aluminum flywheels. Aluminum flywheels are hard to keep tight on the flywheel due to the softer flywheel material and dissimilar expansion rates of aluminum vs the steel crankshaft.
