Which rail extensions

41racing · Feb 12, 2015

Searched on here and other sites and can't figure out which rail extensions I need. I have a 14 st and want to put a 137 on. Seems that 13 and older use cat rail extensions but from what I read those extensions will not work with 14 and newer. If someone can point me in the right direction that would be great. I checked tracks USA and they list nothing on their website.

I'm wondering what rail extention to use for the 2015 st to get it to 137?

WPS Part number is 44-1503 for the rail extensions to go from 120/121 to 137.

These work on the 2011-2014, and should work just the same on the 2015 kits. I said "should" because I haven't personally verified fitment them on a 2015 kit.
You can order them through your local dealer.

One other note- send the extensions to your local powder coater before you install them. That will keep your Timbersled kit looking good, and preserve its resale value. Black spray paint only lasts for a couple rides before it starts to flake off.

That rail extension says it's for a 6 3/8wheel I have t measures the wheel in the mtn horse but I'm guessing it's bigger than that??

I used that part number on my personal kit a few seasons ago, and on many of my riding buddies' kits. Worked great on all of them. They're all still in service.
