I put a 162" x3" challenger X 3 on my '13 CAT HCR , the 85 durometer track they come with is good only for spring conditions , now with the 3", climbs that i had to turn out of for fear of a stuck in the past, now i turn out for fear of the height it will climb to . The 3" will get you to way...
just installed the 20 tooth on my 13' HCR 800 , along with a " X3 " challenger track in 162" , pulls like a tractor and gets up and floats now, best " cheap " mod , oh and pitched the suit case silencer for an HPS .
