Replace 2.6" track with 3"?

Shouldn't be a different rail, if you use the stock polaris drivers you do not have to cut the rail but the chain case sleds come with the splined shaft so you will need that shaft to do the swap.

Or you use Avid or Powder freaks drivers and anti stab and cut the rails and use your shaft, this in my opinion is better way to go. The tracks have to be run way to tight in stock form.

When I did my swap from a 2.6" to 3" lug track on my 2013 Pro, I installed extravert drivers which are located further towards the sides of the driveshaft / closer to the rails. Stock intravert drivers are located more towards the middle of the driveshaft. No need to have shorter rails.

With the aftermarket extraverts, they say you can run a little bit looser of a track, in theory helping with overall HP / more free-spinning track. With the looser track, there is a greater potential of something pushing up on the track and making your rails 'stab' the cut-outs on your track. Hence the name, anti-stab.

Yes you do and only use the MTNTK antistab. It has a heavy duty bearing that unlike other ones will not fail. I have done this and it’s a must to be able to run the track nice and loose.
