Adding your products to cart

These aftermarket accessories make it easier to organize your hookups, protect your frame, and give your truck a sharp, custom look that stands out. Choose from corrosion-resistant aluminum or stainless steel deck plates, available in smooth or diamond tread finishes. Aluminum offers a lightweight, paintable surface, while stainless steel adds a polished shine and long-term protection against rust and wear. Deck plates come in a range of sizes to fit your T680's frame layout and can include recessed compartments for a flush, integrated appearance. The air line boxes are available in top-mounted, recessed, and sectionalized designs for easy access and secure organization of your air, electrical, and lighting hookups. Some options even include LED lighting for better visibility during nighttime connections. Pair your upgrade with Kenworth T680 toolboxes, Kenworth T680 filler panels and Kenworth T680 frame steps. Whether you're upgrading for convenience, function, or style, these Kenworth T680 deck plates and air line boxes deliver dependable performance, smart organization, and a professional look that takes your rig to the next level.

Frequently Asked Questions About Kenworth T680 Deck Plates & Air Line Boxes

What are deck plates and air line boxes used for on the Kenworth T680?

Deck plates and air line boxes are components mounted behind the cab on the truck's frame deck. Deck plates provide a durable covering over the frame rails, while air line boxes organize and protect the air and electrical lines that run between the tractor and trailer. Together they help keep the back-of-cab area clean, protected, and functional.

Will these deck plates and air line boxes fit my specific Kenworth T680 model year?

Fitment can vary depending on the model year and frame configuration of your T680, since Kenworth has updated the design over different production runs. Always check the listed fitment details on each product page, and compare your truck's existing hardware and mounting points before ordering to confirm compatibility.

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 for durability against road debris, moisture, and general wear. Finish options commonly include plain, diamond plate, or polished aluminum, depending on the manufacturer and specific product listing. Check each listing for the exact material and finish details.

Are these parts easy to install, or do I need professional help?

Many deck plates and air line boxes are designed as direct bolt-on replacements using the factory mounting locations, which makes installation straightforward for someone comfortable with basic hand tools. However, if your air lines or electrical connections need to be rerouted or if the fit requires adjustment, having a qualified technician handle the installation is recommended.

How do I maintain deck plates and air line boxes to prevent corrosion or damage?

Regularly rinsing off road salt, dirt, and debris will help extend the life of both aluminum and steel components. For polished or diamond plate aluminum finishes, periodic cleaning and light polishing can help maintain their appearance. Inspect air line boxes periodically to make sure lines are properly seated and not rubbing against the housing, which can cause premature wear.
