Aluminium & Steel Lightweight Flywheels

Lightening the weight of the flywheel releases bhp, less metal to spin round improves engine pick-up.

Alloy and steel flywheels only weigh approximately 4kg, whereas cast iron flywheels weigh approximately 10kgs. In the past, when tuning your engine, the cast iron flywheel came in for some serious attention. As much material would be removed as deemed safe. Years of stress caused by engine revs, heat and clutch abuse, may well have pushed this hard-worked part into an unsafe condition. Flywheels and clutches have been known to fail catastrophically.

For alloy flywheels, the ring gear must be also be pinned once it has been shrunk on. Crankshafts/flywheels can only be interchanged as matched pairs.
