For the chassis skid and a-arm guards I would buy based on price. Check with rocky mountain. For the swing arm guard go with the polaris. You don't have to remove the plastic guard to install it. All of the aftermarket plates require removal of the plastic guard. Even though I broke welds on the polaris I still think it offers better protection by leaving on the plastic. If you go with the polaris guard have some gussets welded in the fill in the gaps between the tabs on the back & going forward. After gusseting it's now rock proof
