maxxperf,for me have had thease on my sled for 7yrs.there the old quick rods(wrench jobbers)but hey they work very well,no ice problems....i wont say it again put composite skis on your sx,transfers rods,144studs and you will have a great trail sled.the tracks that came on the 98 sx were junk IMO to small of a lug.mine fell apart after 1260 miles,went to a camo and it is still in great shape,even with the sparatic snow fall we get here in wny.
