Looking to swap my blizzard Mx’s stock track to a 121” with 2.52 pitch. I am wondering if different drive gears will fit on the same shaft to change the pitch or would I have to completely change drive shafts and gears? Any info would greatly help

You may have trouble with the suspension as its made for a 114" track.

You can buy involute sprockets that will fit on that shaft , but the drive on that MX is quite large , not sure of the size but most involutes wont be as big so ratios change , maybe best to just leave it alone and ride it
