Running a Powerclaw track...

[pura vida]

no offense taken, it's all goooooood....

not only can they ice up but if you track is loose enough that the center extro start to engage you only have one in the center of the track. so all the force is right in the middle which can cause it to flex/stretch, which it then ratchets. so you end up focusing the force/stress into a smaller area. and from my very unscientific observations if it ratchets off the main drivers (which means the track is lifting off of the drivers) then the single center extro isn't enough to keep it from ratcheting and it just ratchets harder with all the force focused in a smaller area. imo, the center extro is more marketing than anything. extros/combo drivers have been all the rage for a number of years and polaris can claim they have the same feature as the other two even if "standard" combo drivers can't be used b/c of the rails.

When it does ratchet it can also tear the rubber off the edges of the track in the center windows, my stock track had a bunch of tears from ratcheting. I can probabley find a pic if interested.
