about to go to canada in 2 weeks. 150 miles on sliders and appear half gone at front idlers. not sure if i want to try and put on about 400 miles in canada based on brp's response. don't want to have to change sliders in canada while my family is there with me. thinking of putting like sno stuff sliders on like i saw on another post. are they harder sliders...more durable?? or would i be better off with a set of graphite sliders?? any particular brand people with SC4 have had luck with?? would appreciate any help. since no good snow figure i may park myself in the garage with the sled and maybe change sliders before i go. what do u think??later!!
