When I bought mine in '09 with only 800km on the odometer, the sliders were toast, mostly at the front curve. It is a problem on some sleds. I think the stock settings from the dealer are on the tight side. Because I do a lot of trail riding and often encounter low snow conditions, I did the following:
- low snow wheel kit in the front at the spot with the most wear
- 135mm wheels everywhere vs. the stock 130mm (I used Doo wheels at the time. Excel wheels are now available)
- clipped the whole track
My sliders lasted over 8,ooo km with this setup. I replaced them only because I had to replace the whole skid.
