Does anyone know where to get just the ASP Crank Pulley? Is it worth the time and money? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

TruckPerformance.com has it at a good price. The pulley is smaller in diameter and weighs about 1/2 as much as stock. It allows the crank to spin up faster and reduces the load on the engine from your accessories. It works. You notice the difference right away. I bought a 16X2X120mm bolt to get the ASP pulley started onto the crank snout. That helps because you know you have enough threads in the crank before the bolt heads bucks up against the pulley to push it onto the crank. You need to put a BIG flat washer on the longer bolt because they don't come with a built in flat washer like the GM crank bolt does.
