Outfit your Peterbilt 367 with durable deck plates and air line boxes built for heavy-duty performance, easy organization, and a clean, custom finish. These aftermarket upgrades create a sturdy, slip-resistant surface that keeps your air, electrical, and hydraulic hookups secure and easy to access. Choose from aluminum or stainless steel deck plates available in smooth or diamond tread finishes and a wide range of sizes. Aluminum gives you a lightweight, paintable surface, while stainless steel provides long-term corrosion resistance and a mirror-polished shine. The air line boxes in this lineup make connection management simple. Pick from flush-mount, recessed, or sectionalized designs-each with integrated cutouts for air, electrical, and hydraulic hookups. These configurations help keep your lines organized, protected, and ready for quick access. Pair your upgrade with Peterbilt 367 toolboxes, Peterbilt 367 filler panels and Peterbilt 367 frame steps. Whether you're upgrading a single component or building out a full rear-frame system, these products deliver strength, flexibility, and style. With versatile mounting options and precision craftsmanship, Peterbilt 367 deck plates and air line boxes give you the functionality and reliability you need for long-haul work or on-site performance.
