So I just wanted to give the community a heads up. I bought this tensioner from brenspeed.com and about a year after the install with my supershaker I noticed a belt/pulley squeak. So while I was back in Virginia before I shipped my car over to Hawaii I was getting some work done to freshen the car up for my tour in Hawaii. I asked my speed shop to look in to the source of the squeak. I figured water draining out of the supershaker skirt might have rusted out a pulley (thought it was more the idler at fault). Come to find out it was the billet pulley upgrade for the tensioner. What happend was road grime/dirt gets on your belt and the pully and wore a grove into the pulley which split/cracked my belt into three strips. So the spare belt I had bought came in handy and the shop took a factory pulley and reinstalled that into the Steeda tensioner. So just an FYI that apparently billet pulleys will wear out and crack your belts, wish I would have known that and saved the money...
