Larger Upper Wheels to Prevent Track Rub on Monoshock

Travis, I think the better option is to manufacture a wear plate to slide over the end of the mount that will cover the top of the shock with steel. Then the bolt through would hold it on. I have welded plates on a couple monos in the past to accomplish this but from your side, just a simple u shape with the curve made on the lower part of the u so it wont catch.

Most of the sleds i have had in that show major wear, also have upper bushings that have major wear. The shaft is fixed to the frame, the arm is on the shaft with bushings. the shock is pushing up and back. Any slack in the bushings from either being worn or the aluminum shaft being warn will allow the shock and mount to move back and up causing the issue.

One other cause is warn out internal drivers. Guys running the track banjo tight to keep the track from ratcheting on worn out drivers. Look at the track bowing down when the track is really tight. Normally the track only bows down when you wack the the throttle. When it's tight, it is always down.
