The ATI damper is an aftermarket replacement for the harmonic damper on the front of the crankshaft. Generally, aftermarket dampers are used for high rpm applications where the stock rubber ring unit might come apart.

Thats what happened to me. That little rubber piece gave out and I had to buy a new one. Dont know if its an aftermarket one or not. It cost me around 100 bucks for a new dampner and 325 in labor because the mechanic had to remove my steering rack. Just a question though, am I going to have to worry about this new one going out?

A new ATI balancer is about $ 450-475.00. They are a zero balanced unit that is SFI approved and is mainly designed for high horspower and/or high rpm applications. They are also rebuildable.

Note that they are only 10 % underdriven vs. a ASP that is 15%.

If you order one make sure they give you the A/C pulley!
