Simple instal. I did it on my 2012 163" and I liked it a lot. It defiantly changes the charictoristics of the machine in a positive way but it will never be an xm. They changed so much geometry from 2012 to 2013 and most of it is in the front end. I did not change out to a flex edge track and I still felt a noticeable difference. For me it was a great change and well worth the cost. Hope this helps
I installed it in my 2011 freeride, you can tell the difference. The flex edge track may make it more maneuverable but for the money I would say to try it first. As said the instructions were a bit vague. They said you couldn't install it in the freeride but I did.
Installed it and the track in our 09 xp. It made a very delightful upgrade and got rid of the cheese grader track. It's not the same as my xm's but really close.
Did it on my 09 XP last year. Original track though It helped a lot. Doing the S36 front end kit right now along with the spindles and New skis. Will update once the snow flies LOL! I agree that the install was simple but Vague instructions.
