Looks like GM and the aftermarket suppliers have discontinued that part. That generally means you either find one at a dealership through their parts finding system or get a used one from a salvage yard. What is wrong with the one you have? You might want to look at one of the aftermarket tensioners sold for the LS4 engine.
