IMPROVE THE PERFORMANCE WITH LIGHTER PULLEYS

The Cusco Aluminum Pulley Set has been designed to improve engine response by reducing rotational mass generated by the weight of the factory pullies. The crank pulley included in this kit weighs just 1.74LBS (790 g) when compared to the stock crank pulley which weighs 5.07LBS (2.3kg). The other pulley included in this kit is the alternator pulley which weighs 0.16LBS (76g) while the stock alternator pulley weighs 0.66LBS (300g).

The result is less stress on the engine which will improve throttle response and acceleration. These pulleys have been fabricated from high-grade metal materials, and they will come powder-coated in Cusco's flagship blue finish to provide extra protection against rust and corrosion, and to add a nice touch to the engine bay.

Installation takes about 2 hours.
