I was on camoplasts web site and saw that they make a 2"- 146" chalenger track in the 2.86 pitch. Would this be a good track to upgrade to on my assualt, having the shorter lugs it should offer the required clearence but was wondering if it would be worse for traction that the stock comp track? This track also has no center port but i have a drive shaft from a 06 rmk 600 with stock drivers. Would that work with this track? I had this track on a 144 rmk with a 660 and I thought it worked really well but at the time it was the tallest lug availble. I do realize that the 2.5 camo extreme would be best but dont want to do a drop and roll. I know some have done it without but just not sure if i would be happy how it would perform as a drop in replacement. How would the challenger compare to the polaris 5.1? Thanks for any input and sugestions.
