Got this for my frontrunner 2002 Chevy LS 4WD and it was perfect. Removed squeaks from my car. I installed it myself, it's pretty easy. First remove the belt, remove and replace the screw, and then reinstall the screw. I bought a torque wrench but you don't need it, just apply enough pressure to tighten it and then retighten slightly. Also check the belt for tears and the Gatorback is a good buy.
