I went with a stock tunnel extension from Barn of parts and used track usa tipped rails, overall very happy.

Any one have experience with the star relocate kit and a 136" rail extension to get 144". Any issues or
tips on making it work. would like to try it for the shallow approach angle.
I went from a 121" rtx to a 136" with a Star relocate kit and a 4" Tracks USA rail extension. I recommend the relocate as the first step in extending rails and if going longer than a 136" I'd also recommend using the tipped rail extensions (the 4" extension I used are to short to add tipped rails). The spring on the front skid shock should also be upgraded to better match the approach angle change when using the relocate kit. I installed a custom dual rate spring from Hygear.
I actually liked the Nytro better when it was at 128" with the relocate for riding the tight trails in this area but with it now at 136" it does much better in deeper snow and handles the rough trails well. Extending out to a 144" wasn't an option for me because at the time I wouldn't have been able to trailer it. I also believe a 144" wouldn't fit my needs for the type of riding I do here in western NY.

I added the star relocate on my 2013 Nytro, being the 2013-14 nytros came with 2.86 pitch drivers the short track was 120”, not 121” like previous years so by adding the star kit it will move the suspension back if I remember about 4 inches which made me use a 129” 2.86 pitch track, 2008-2012 Nytros would need a 128” track with the star relocate kit being that they were 2.52” pitch tracks.
You can add any extensions you want you just have to do the math and get the right track length.
