Benefits of Bed Caps and Rails

So, why install bed rail caps and a tailgate protector in the first place? Whether you use your pickup for work or play, it’s bound to collect scratches, scuffs, and minor dings around the bed—particularly on the tops of the bed rails and tailgate. Rather than settling for normal wear and tear, prevent it altogether with a set of premium bed caps and a tailgate protector.  

These components cover your pickup’s upper bed rails and tailgate top, taking the brunt of the damage to maintain your truck’s resale value and the underlying paint’s like-new finish. Not only do these protectors guard against damages, but they look great while doing so. Bed rail caps and truck tailgate protectors are available in numerous finishes and materials, ranging from texturedblack plastic to sleek,polished diamond-plate aluminum. Some even include integrated LED lights for enhanced visibility while loading and unloading cargo.
