Pro Ride Quick Drive 2013 VS 14 & 15

Looking to gear down my 2019 RMK 155. Is there a difference between the 2013 pulleys vs the 2014 and 2015? I see they use different 44 tooth gears. Is there any reason why I wouldn't want to use a 2013 part number vs a 2014+?

There were a lot of bolt failures on the bottom gears in those years and at the time we thought the change was new tighter tolerances because a rocking gear means the bolt will fail. Later we realized we saw rocking gears on all years at least up to 2017 if not even on the latest models. The thing was, it was different from one machine to the next. The only way you will know is remove the bolt and belt and rock it back and forth.
I would have no problem using gears from any year if they fit tight. The belts from 2013 did suck though.
