International LT Deck Plates & Air Line Boxes

Frequently Asked Questions About International LT Deck Plates & Air Line Boxes

What is the purpose of a deck plate and air line box on an International LT?

The deck plate is the flat panel located behind the cab that provides a mounting surface for air lines, electrical connections, and the fifth wheel area, while the air line box houses and protects the glad hand connections and electrical plugs that link the tractor to the trailer. Together they keep these critical connections organized, accessible, and shielded from road debris and weather.

Will this deck plate or air line box fit my specific International LT model and year?

Fitment can vary depending on the model year and cab configuration of your International LT, so it is important to check the listed specifications and part numbers against your truck before purchasing. If you are unsure, comparing your existing part's dimensions and mounting pattern to the product listing, or contacting our support team with your VIN or model details, will help confirm a proper fit.

What materials are these deck plates and air line boxes made from, and how well do they hold up?

Most deck plates and air line boxes are constructed from aluminum or steel, chosen for their balance of durability and resistance to corrosion from road salt, moisture, and general wear. Aluminum options tend to resist rust better over time, while steel components may offer added rigidity, so the right choice often depends on your climate and how the truck is used.

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

Installation typically involves removing the old unit, transferring or reconnecting air lines and electrical wiring, and securing the new part with the existing mounting hardware. Basic hand tools are usually sufficient, but because these components involve air and electrical connections, it helps to have some mechanical experience or to have a qualified technician handle the installation to ensure everything is properly sealed and connected.

Can I get a deck plate or air line box in a specific finish to match my truck?

Many of these parts are available in raw, painted, or polished finishes depending on the manufacturer and specific product. If matching the look of your cab or achieving a certain level of corrosion resistance matters to you, check the product description for available finish options before ordering.
