I know these forums might not be the exact place to be selling supercharger parts but giving it a shot

Its a genuine Track dog racing belt tensioner for your JACKSON RACING supercharger. allowing 2" of adjustment. stock tensioner that comes with your jackson racing kit only allows 1" and uses the shitty plastic pulleys.

One pulley is missing so reason why price is so cheap even though you can get a new pulley off ebay for about $20 bucks..

Original price is
price for bracket: $50.00 shipped!

 

just to make sure for others. you do have the peace that goes in the slider that the pulley bolts to?? if yes then this is a good price. the pulley you need is also the same you use for the timing belt, they are cheap.

 

the piece that goes in the slider is just a bolt and nut. exact same thing that holds down the other pulley shown. Extra nut and bolt is alll you need along with a new pulley
