I just got an 8'6" Xtreme V this month and love it. The deal however put the long stops on so i couldnt stack as high so i went back to ask for shorter ones. They told me that it would void the warranty because they have had problems with the lift chain coming into contact withe isolation module. I put on the shorter stops anyway because a buddy of mine has the same plow with the shorter stops. I have my plow positioned in the bottom hole as well and theres no way that the lift chain will ever hit the isolation module. Just wondering if anyone has damaged there isolation module due to the short stacking stops? If you did which of the three holes was your plow in on the push frame? I could see maybe if you were in the top hole then the plow could go even higher and possibly hit then but then you dont get as much of an attack angle as you would with the bottom hole.
