Drive shaft / drivers interchangeable

[Polaris 101]

Iam looking to upgrade my wife's 2014 600 assault stock cobra track with a 146 2.4 track that I found a great deal on. I don't want to just swap out the drivers but instead just change the whole driveshaft assembly. I have found a few used ones from 2011 pro 800s is the driveshafts the same length and size on all new pros with chaincases? thanks

Yes all Chain case'd PRO's use the exact same part number driveshaft. Note the flat lander sleds will have different pitch drivers but the drive shaft itself will be the same.

Thanks! looking over part numbers they are different because of the different pitch. Hers it a 2.52 144 with no center driver and of course the one off the 2011 pro rmk will have the center driver and a 2.86 pitch. How well does a 2.4 clear in the assault and is this a wise choice on a track. I found a 5.1 146 2.4 new for 400 shipped vs 700 shipped for a new 2 inch challanger thanks again

The drive geometry is identical, It will fit the same as the RMK and PRO RMK. The only time you will have an issue is if you try to downsize to the 7 Tooth driver (chain case interference, requires the chain case mod to the front corner of the oil well), but for the 2.4" you do not need to worry about that.
