I have a yamaha rhino, already with greaseless clutch sheave and 686 kit. rhino does 65 mph. A birdie told me that the yamaha grizzly ring and pinion is taller gearing than the rhino, and that they plug and play. Is this true, and if the grizzly ring and pinion is taller but not compatible with the rhino difs, will the grizzly difs bolt into the rhino or need slight mods to it? anybody who has knowledge about this please let me know. thanks.
