I have one. They are better, less vibration on the crank and chain. the stock one is fluid filled. Plus it is SFI approved if you go March like I did. It was a sexy looking piece as well. Plus it comes with an overdrive pulley for the Alternator so you dont loose any battery power.

almost all of them are the same. look for ones that have a raised lip so you don't throw the belt off at high rpm. Just keep an eye out for one that is on sale, unless you need this one now. I have a powerbond one and I have never had a problem with it.

you can make around 10rwhp with a cam. You really only see it in the top end. I would only put one on when doing a cam. Its one of those might as well while you are in there type of things.
