The Peterbilt Shock Covers by Roadworks are a practical and stylish addition to any truck. Made of stainless steel, this kit includes two pieces that conceal shocks and air bags. It uses factory bolts and additional screws to mount on the back of the sleeper. With six bulls-eye light holes, you can choose from a variety of lighting options to customize your truck. These covers fit 2006 and newer or 2005 and earlier models, but not day cab or 70" sleeper trucks. Roadworks offers a 1-year warranty for added peace of mind. Call for more details.
