DON'T buy the Mopar ones. They are cheap cr@p. If you can find em for $10 or under they MAY be worth it. They do absolutely nothing except add a place for brush to get stuck in on the trail. I got em and would have spend the extra $30 or so to buy the metal ones if I knew what these really were when I bought the KJ.
