Armond, I tried to run an ATI dampner but had a big problem with metal transfer, ruined 6 or more hubs , talked to ATI several times to try and get different rubbers and got no help so I switched to a Fluiddampner and have had no problems since I changed. However since then I was talking to Glen Self and he said to ask for (I think is was) 88 rubbers that they would work. The ATI web sight showes different durometers and different weights if you can talk to the right person I sure they could help out. I don't know anything about stock dampners
ATI has a chart that shows a graph of the different types of dampers VS RPM the fluid style is best 4000-5000 RPM, VS ATI then 5000-6000 they are the same then over 6000 RPM ATI is the best, since I don't go much over 6000 I guess that is why it works so good on my setup.
