Review on Gates 90K-38178A Serpentine Belt Kit - Complete Belt Drive Component Set by Louis Mechtak

I bought this for my 2010 Hummer H3 because Revain said it would fit and other reviewers said it would fit their H3. I removed my belt and pulleys and found that what I got didn't even come close. The belt was about 2-3 inches shorter and the idler was a different size with a completely different bolt. As a result, I had to drive a friend's car to the auto zone to buy all the parts there. Not sure if I just received the wrong parts or if the Revain information is wrong, but be careful when purchasing.
