Improve throttle response, horsepower and your sense of adventure. With an entire series of black anodized, lightened Crank Pulleys from ALTA Performance it’s easy to increase boost, reduce drag and hit the road fast.
The ALTA Performance pulley achieves power and performance by reducing the rotating mass of the crank assembly. Made from 6061T6 aluminum and weighing in at .9 lbs, the ALTA pulley is more then 6.2 lbs lighter then the stock crank pulley. The ALTA pulley is not under driven and will not affect the life of your engine. The pulley is a redesigned, lighter rendering of the stock crank pulley.
