The PERRIN Lightweight Crank Pulley weighs in at just 1.2lbs, which is about 4 lbs lighter than the OEM crank pulley. Lightweight crank pullies are safe to use on boxer 4 cylinder engines due to the shorter crankshaft length. The reduction in rotational mass results in more horsepower, and a better throttle response.
This Lightweight Crank Pulley has machined grooves that will work with OEM, as well as aftermarket belts. The PERRIN crank pulley is machined from 6061T6 billett aluminum, anodized red and laser etched for increased belt life and a precision fit.
