Enhance your Kenworth T300 or T450 with aftermarket deck plates and air line boxes built for durability, safety, and style. These upgrades make it easier to manage trailer hookups, protect your frame, and give your truck a cleaner, more professional appearance.

Upgrade with New Kenworth T300/T450 Catwalk & Deckplate Designs

Choose from aluminum, stainless steel, or diamond tread deck plates designed to handle the demands of daily use. Aluminum offers a lightweight, paintable surface, while stainless steel provides a bright, polished shine that resists corrosion. The diamond plate finish adds extra grip-ideal for climbing, loading, and working around your rig. The air line boxes in this lineup keep your air, electrical, and lighting hookups secure and organized. Go for a recessed or flush-mount box if you want a smooth, integrated setup, or choose a top-mounted box for quick, easy access. Air line boxes can be ordered with blank or pre-drilled designs to fit single or dual trailer hookups. Combine your upgrade with Kenworth T300/T450 toolboxes, Kenworth T300/T450 filler panels and Kenworth T450 or T300 frame steps. Whether you're upgrading your rig or replacing worn parts, these Kenworth T300 and T450 deck plates and air line boxes offer the reliability, protection, and polished look that every driver and fleet owner can appreciate. Built tough for real road conditions, they deliver lasting performance and everyday convenience.
