GNP's Billet Lightweight Alternator Pulley has been CAD designed, CNC milled from 6061 T6 aluminum and anodized to protect it and give your engine bay some "bling".
GNP pulleys are the same size as stock, and are not under-driven. They are intended to work with your vehicle's stock belts, eliminating the fuss and hassle of hunting for special length belts.
These Lightweight Alternator pulleys work very well with out lightweight crank pulley.
As most lightweight pulleys do, they do not create horsepower, what they do is promote engine responsiveness by reducing rotating mass, which results in quicker power delivery.
By decreasing the parasitic effects that factory accessory pulleys have on a vehicle's engine, his reduces rotational weight and increases responsiveness and efficiency.
