I think I paid like $90 or so for it last year from procharger. Take $40 for it. I also always consider trades. Needing a wot box at the moment. Would trade and give some cash.
Well with the procharger belt tensioner systems its basically a one size fits all I believe. When I ordered it they asked me no questions at all just sent me the belt. I was running a 4.5 pulley. But had a 4.27 pulley on once as well. Plus you can move your idler pulley and adjust tension with a procharger.
