Whys that? Whats wrong with the stocker? Its saved my ass end a couple of times, had to pry it out from the rotor once because i got a rock! If your dune riding maybe i could see getting rid of it, but id rather have one on, theres no reason not to run it besides maybe a little bit of weight savings.
Im sure others will chime in, maybe im wrong and there is a good reason to get rid of it, i just dont see it. As far as other skidders to try i dont know the stock one seems to do the trick.
