Upgrading or replacing the 48-inch by 4-inch sleeper panels for Freightliner Cascadia adds a refined exterior trim look while providing a blank surface ready for lights or custom touches. These chrome-plated stainless steel panels are sold as matched driver and passenger pairs and fit Cascadia 113 and 125 models from 2008 through 2018, offering corrosion resistance and a polished finish that complements your truck's sleeper section. You can choose blank panels or versions with 13 bullseye cutouts or three universal light cutouts per side (lights not included), depending on how you want to integrate lighting into your build without extra drilling. Because these are high-quality aftermarket replacements rather than OEM, they provide a cost-effective way to refresh aging trim or support styling projects. Each set carries a warranty against defects in workmanship and material from the date of purchase, and panels ship directly from the manufacturer, which may mean they arrive separately from other order items. Before buying, confirm fitment for your specific Cascadia model year to ensure proper compatibility and installation.
