Body protection is one of the first mods we make to nearly every Jeep we own. Even if you don't care about dents and dings, a smooth corner or rocker will skid over rocks and obstacles better than meat-hook-like, jagged, bent-up body metal. So to keep the body of our LJ smooth and clean, we opted for some protection from Poison Spyder Customs in the form of the company's Rocker Knockers, Trail Corners and Tube Fenders. Each component is available for CJs, YJs, TJs and the Unlimited (LJ). All of the parts are easy enough to install at home. Here's how they go on.
