There are a number of different ways to accomplish what you are talking about.
I put on 144 rails and a 151" track on my Tcat this summer. Moved the rear skid back and the new rails used a bigger rear wheel than my old ones. Something you might consider doing is adding short extensions and moving the skid back in conjunction with a big wheel kit. You will probably have to extend your tunnel and coolers. The coolers are the biggest problem I had but its all do able. I posted a fairly detailed thread on my project this summer.

But i think you just gave Max a massive coronary, LOL
Pretty scary to see your sled in that many pieces.
I might be wrong here, but that may be a little more involved the Max thought.and i suspect this is more for trail.
Max, i haven,t done it myself ,but to keep it simple,rail extension,and a tunnel ext,136 track.
If you go with the big wheels,i believe you are now getting into relocating suspension mounts on the tunnel,unless you find a rail ext that made for big wheels
the coolers will work fine as is
yeh kinda like whats been said you can either get rail extensions or you can buy brand new 136 rails..then you can buy the tunnel extension that I think just rivits to the back..Iv seen lots of edgeX set up like that..
Talk with Mountain Machines Performance about any extenison or relocation needs. They will hook you up with what you need. Plus they are the only ones that will warranty their billet wheels if you bend or break them! They have a huge fan base on snowest.com. Great customer service. Maria and Steve are great people to work with and back up their products.

Last time I was on Polaris' web site I was looking through the parts and they have complete kits to install a 136" track.It comes with longer rails, tunnel extension, and everything else minus the track.That would be friggin great on my Pro X 600.I'm not sure what other models they make it for though.
