Adding your products to cart

Upgrade your Kenworth T800 with durable deck plates and air line boxes designed for long-lasting performance and a clean, custom finish. These aftermarket accessories make it easier to manage your air and electrical hookups while giving your rig a professional, organized look. Choose from aluminum or stainless steel deck plates available in smooth or diamond tread finishes and a variety of sizes. Aluminum offers a lightweight, paintable surface that's easy to match to your truck's color scheme, while stainless steel delivers a bright, mirror-polished shine that resists corrosion. Many setups also double as secure storage areas for tools and gear, helping you stay organized on the road. The air line boxes are designed to integrate seamlessly with your deck plate setup. Choose from recessed, on-top, or low-profile coffin-style boxes depending on your preference for access and appearance. Each one provides a convenient, protected space for managing air, electrical, and lighting connections with clean routing and easy maintenance. Pair your upgrade with Kenworth T800 toolboxes, Kenworth T800 filler panels and Kenworth T800 frame steps. Built to handle the demands of the road, these Kenworth T800 deck plates and air line boxes combine rugged durability with polished style-perfect for owner-operators and fleets looking to upgrade both function and appearance.

Frequently Asked Questions About Kenworth T800 Deck Plates & Air Line Boxes

What are deck plates and air line boxes used for on a Kenworth T800?

Deck plates and air line boxes are mounted behind the cab on the frame rails to organize and protect the air, electrical, and hydraulic lines that run between the tractor and trailer. The deck plate provides a flat mounting surface behind the cab, while the air line box houses and routes the glad hands, electrical cords, and hoses so they stay secure and out of the way during coupling and uncoupling.

Will these deck plates and air line boxes fit my specific Kenworth T800 model year?

Fitment can vary depending on the model year and how the truck was originally configured from the factory, including frame width, existing mounting hole patterns, and the style of air line box previously installed. Always check the listed specifications and compare measurements to your truck before ordering, and reach out to our team if you are unsure about compatibility with your particular setup.

What materials are these parts made from, and what finish options are available?

Most deck plates and air line boxes are constructed from aluminum or steel, depending on the manufacturer and specific product. Aluminum options are lighter and naturally resist corrosion, while steel versions tend to be heavier duty. Finish options commonly include raw, painted, or polished/diamond plate surfaces, so you can choose based on the look and durability you need for your truck.

Do these deck plates and air line boxes come with mounting hardware, or will I need to source additional parts?

This varies by product and manufacturer. Some deck plates and air line boxes include the necessary brackets, bolts, or mounting hardware, while others are sold as the plate or box only, requiring you to reuse existing hardware or purchase mounting components separately. Check the product description carefully before purchasing to confirm what is included.

How difficult is it to install a replacement deck plate or air line box myself?

Installation difficulty depends on whether the new part matches the existing mounting points on your frame. If the bolt pattern lines up with your current setup, installation is generally straightforward with basic hand tools. If the new part requires different mounting locations or modifications to existing brackets, the job becomes more involved and may require drilling or fabrication. Reviewing fitment details and comparing them to your current configuration before buying can help you gauge how much work the install will take.
