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
