Didn't last 220 miles.
My6 husband bought these for a 2004 Polairis Edge.  We have a lot of ice on the trails and he wanted to keep the slides lubed.  He made 2 trips about 110 miles each  in 2 weeks and most of the product disappeared. He was driving on ice, snow covered tundra. He's disappointed. He installed them about midway on the rails as he couldn't fit them farther forward. So maybe installation was an issue. Also he had to cross steep ice ridges on some rivers that go up and down w the tides - rough going there - but bottom line for them to break apart in 2 wks is not cost effective.
