Driveshaft interchange question

[BigAir]

Can anyone confirm that the driveshaft out of a 2015 Polaris Rush 600 will fit my 2018 RMK with belt drive? The shaft looks the same as a RMK steel shaft, but impossible to know for sure looking at pics. Swapping to a 3" and have decided to go with a steel driveshaft at the same time. Can't go by part numbers, because they only sell them complete with drivers and the sleds use different drivers.

I put one in my 2016 800 AXYS no problem. You will need new drivers for the 3" pitch track though. The 15 will have 8 tooth with 2.86" pitch

It's out of a trail sled, not a RMK, so I'm guessing it will actually have 2.52" pitch drivers. Either way I am planning on 3" pitch Avid drivers.
