Rail extensions kit - everything you need to extend your snowbike's rails by 4.5" to turn a 120" track system into a 129", or a 129" into a 137".
137" to a 146? You're crazy! But it can be done!
Compatible with Yeti SnowMX rails from model year 2017 and up.
The Timbersled option is for Mountain Horse rails where the rear end looks like this - that's most 2013-2016 kits and some 2017s (SX).
If there's enough interest it is possible for us to develop a setup for ARO rails.
Parts for left and right rail included. Track sold separately
