FYI to get rid of the overheating on hard pack trails...you pull over and cut a block of snow maybe 6 to 10 inches deep and 18 inches wide by 2-1/2 feet long depending on length of sled and you put that on the rear tunnel on top in rack or whatever ya got to keep it on there....then as you ride it melts the block and cools the coolant in exchanger under there with no overheating for miles of smiles...rinse and repeat as needed along the way
unless you own a m

again studs are great if running hard pack or ice
not really needed if you run soft sno w all the time .if a,sled has studs in nice shape call it a bonus .
