I've had a good year but lost the tensioner and the belt broke. Well, Gatorback belts are getting harder and harder to find locally, and I needed to keep working on the truck, so I bought a Gates belt from my local parts store. He slipped and jumped his teeth and the generator light went on because he couldn't spin the generator fast enough. Needless to say I'm glad Amazon had this on Prime and got it delivered to me in 2 days, the Gates belt is back tonight and I also got a new set of pulleys so this belt should last a long time. My Goodyear belts have done 30,000 miles in the past with no problems, I think it's a good buy and the price on the web is very good too.
