I have a 2012 Fat Bob & I put the 56267-09 pull back Risers. And I having the same problem as many others about the bars twisting. Quite a few people are talking about these poly Bushings for the cure. Does anybody know the part number & where I can get them? thanks for listening.

 

Any HD dealer - if you want to spend the most. Or you could just Google "Polyurethane Bushings" with your year, make and model.

Hopefully your all using the shorter bottom bolts they come with. Mine moved around before with stock risors. And the 6" only mag. The issue . No real biggie. May have a try the poly bushings.
