Hey yall since i returned my cat-back exhaust to summit i got $110 in store credit so i decided to go with a set march performance pullies. they specialize in serpantine set ups and pullies set ups, anyways i got their "combo" witch is a alternator pulley and a crank pulley. The alternator pullie is aluminum as well as smaller so you can keep the stock amp out of the alternator because the crank pullie creats the underdrive effect witch is where the crank pulley is made smaller so that it slows down all engine accesories. But moving on they sent me the right pullies but the wrong set of information so i bought the belt that closly matched my motor witch was a 93-97 s-10 4.3L belt, and it worked fine, it is very tight and their is no slack.

Since installing the pullies the RPM jump up much quicker and acceleration is much improved it is well worth the money, i dont know of anything else you could buy that would make that much of a difference. Anyways just letting yall know

 

It is good to know that. not many ever really tell what something did for their truck. so thanks for letting everybody know.
