No, but it's as deep as it will go.

I think when I ordered it, I told the guy at ATI I didn't care about pulley depth and he said this damper/hub was the best one to use. It's been long enough that I've forgotten exactly, but that's what I recall. ATI 918282E

It just slid on? Every aftermarket damper I've ever bought new needed to be honed to a light press fit. I don't remember the number now but there is a spec. If it were mine I'd call ATI and check.
