Mainshaft support...
We changed my sons shovel head into an open belt drive and needed this bearing support. We also had the super nut, on the mainshaft and made a couple of Spacers And it fit perfectly. He has been running the Bike For about a month now with zero problems. If you do not have the super nut on your bike, I am confident it will fit without modification. Excellent product!
