144" Airwave?

Does anyone know if the M20 will still work if stretched to 144"? On the TEAMFAST website they only off a 144" skid in the M10-W2 version with the live rear axle, so I am a little worried about track tension problems on the standard M20 skid if I extend it out to 144".

Are you going from 136 - 144 or 121 - 144? You would probably be ok if only going 136 - 144. That will move your rear axle back 3.75". 121 - 144 moves your axle back approx. 11.25" and that worries me a little.

TeamFast, of course, does not recommend doing this. I think the biggest issue, like you mentioned, is track tension. Does anyone offer bolt on extensions for the M20?

If you do extend, install extrovert drivers and run your track as loose as possible without it ratcheting. I run 1.5" of track sag with my 151" W2. It looks like it would peel off, but it has never caused any problems. I trail ride in UP 95% - off trail 5% , no studs.

Tracks USA sells a tipped 121 to 144 extension for the M10. From what I can tell, the M20 rails are identical to the M10 rails. I do have extrovert drivers, so I will hopefully be able to make up for any tensioning problems by running a loose track.
