    10% crank pulley belt size

    From what I understand, using a 10% crank pulley requires a new size jackshaft belt. What Size would I need? I would have a 10% crank and a 5% jackshaft pulley

    You'll need a 43.5" belt.

    So who makes this belt and/or what is the part number? I called Napa, the stock belt length is 43-1/8, the next size up they show is 51-1/8.

    Gates K080435 for an 8 rib if you have an 8 rib JS pulley, you can just trim off one rib if you can't get a 43.5 in a 7 rib.
