DO ME A FAVOR. Call ATI AND TCI and tell them that you have one of their dampers that you bought back 18 months ago and it now no good. Get back to us with their response.If they are willing to replace it,you know where to buy your new damper. What product have you bought recently that has a 18 month warrenty?Most likly 30 days.Seems to me 440 Source is always brought up to be the whipping boy. I remember the rattler damper ruining a few motors back a few years ago.Some of you guys should use the ignor option when a 440 source post is made.

If the MODS did their job I would not be hitting the notify MOD button. LOL
