Bed rails top your truck bed with the wicked appearance of smooth black or mirror-polished steel. A matte finish can lend a tough edge to your vehicle. Or, some extra shine can do your truck's body good and is sure to turn heads. Bed caps can bring smooth and rugged looks with the best of them, too–not just for a fresh appearance, but also for covering old marks. Premium protection for the paint on your bed rails A key function of bed caps and bed rails is stopping damage before it hits your paint. Loading boxes, tools, bikes and more gets much less precarious with your bed top protected by a set of bed caps. And, they're custom-molded to the exact shape and size of your vehicle, leaving no space uncovered. Bed rails are also effective guardians, rejecting items that would otherwise dent your bed. They keep large cargo from bashing either at the cab or at the gate, along with safe containment of stacked loads thanks to heightened tie down points.
