Don't know if anyone has tried this; I installed 2" spacers up front and of course was having UCA contact problems. I took a 0.5" heater rubber tube and cut it through on one side, opened it up and fastened along the inside of the UCA contact area-- works like a bump stop. Took the X out hiking on 25 miles of severely pot holed gravel road and it has worked like a charm so far. It stayed in place, showed no wear, and best of all no "clunk" noise anymore. Only time will tell if it will last, about a three buck mod. Have photos, but don't know how to attach.
