Description
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.
There is a Timbersled option is for Mountain Horse rails where the rear end looks like this - that's most 2013-2016 kits and some 2017s (SX). And another style for the ARO/Riot platform.
Parts for left and right rail included. Track sold separately
