It will fit with stock drivers but is a little tight to the coolers or you can run 7 tooth drivers for more clearance. I'm running stock drivers. Just ground down the cooler fins that were tight to track. Rode all last season with no cooling issues. This is one of the better mods for a 1100t. With all the extra traction you need to add a coupling device to keep the skis down. Either OVS wheelie control for stock skid or go timbersled or Kmod.
Im running the 3"CE on my 13 M8 PC. Stock drivers. Track hooks up like nothing else. No problems in 600miles. As stated above it does wheelie alot. Turbo going on my sled now as well as Easy Ryde so that will take care of those issues!
