Rocker guards are a great investment and they do a good job of covering up our less-than-perfect bodywork. The parts are mounted with threaded inserts, which are loved and hated. They allow you to mount to a surface without being able to access the opposite side, but if they don’t sit correctly, you’re in for a long day. Installation can be an exercise in patience. We started with the middle and worked our way out, drilling two holes at a time. Don’t think for a second that lining up ten threaded holes is easy, but the finished results are worth the effort.
