THE 4 KEYS TO TRACK SELECTION
Is the inside circumference of the track and is calculated as the drive pitch multiplied by the number of track segments. It must be correct to the nearest inch for proper fit without additional modifications to the skid frame.*
Is the measurement across the track and is governed by the width of the tunnel. § A slightly narrower track is permissible, like a 15″ track in place of a 16″ track, but not necessarily the other way around
Is the drive cog center distance around the circumference of the cogs on the drive axle. It must match the existing track or the drive cogs must be changed.
§ 2.52″ primarily machines manufactured before 2007
§ 2.86″ especially on recent models manufactured after 2007
§ 3″ and new 3.5″ drive pitch for lowest weight on select mountain sleds
Is the distance the lugs extend above the track surface.
§ 1″ – <1.5" – trail
§ 1.5" - <2" – on/off trail
§ 2" and greater – deep snow
* Aftermarket parts are available for mods when needed
** Some other drive pitches are also found on older models
***Check for adequate clearance before going to a taller lug track
