Part #6702
Aluminum Overdrive Water Pump Pulley
This new pulley is a 10% overdrive unit which will spin the water pump a little more quickly, which gives slightly better cooling.
It is almost 3/4 of a pound lighter than the stock steel unit! That may not sound like much in terms of a weight savings, but since it is rotating weight, it is a good weight savings.
It's made from 60-61 aircraft grade aluminum for lasting quality. And since it is machined aluminum, it also looks much better than your rusty, steel one. It will work perfectly with your stock crank pulley or the underdrive pulley we also have available. Whatever serpentine belt you are using remains unchanged. Each pulley comes with four new stainless bolts.
