![]() I need to know if I can keep the stock belt when using aftermarket pulleys (aluminum BBk or MAC, accepting other suggestions...)
I have to get this topic clear before ordering. Thanks in advance

![]() It all depends on the manufacturer of the pulleys. Most times you will need to buy a new belt. Most pulleys underdrive accessories by increasing pulley size, some kits offer a smaller alternator pulley to regain battery charging and the stock belt can be retained. It really depends on what you're buying.

![]() I agree with 84lx89gt , one thing you can do is put the stock belt on and see how much slack is left on the belt. If is seems to be a little loose then go one size down. But if the belt is tight then is should be fine. I got the ford motorsport pulleys on mine and i had to get a shorter belt.

![]() I'm running BBK underdrives with a new stock belt. You can loosen the top alternator mounting bolt and move the alternator as far out as possible to help put the tensioner back into range. I did this and was able to move the alternator about 1/4-1/2 inch out.
