While the ATI is very good, i've seen more reputable vendors prefer the Fluidampr over the ATI because of maintenence. My vote is also for the Fluidampr

Heard too many times that the ATI needs adjusting or fails or whatever, fluidampr is proven time and time again.

The ATI is larger than stock and overdrives the accessories, spits belts off that break tensioners.. I had it happen 3 passes in a row before we narrowed it down.. Procco has the exact same failure on the same track and thats when i narrowed it down to us both running ATI.. I swapped to fluidampr and the issue never reoccured.. Dont be a victim, swap before you hurt something.. when the belt jumps midpass you lose waterpump and then the motor if it gets too hot..

Not sure if it has to be pressed on but i do believe it's installed in 2 parts the hub section and then the outter portion goes on w/ multiple small allen head bolts.

This is what i run:

I believe that's correct. I think the timing sprocket is incorporated, but I'm not 100% sure about that part.
