Peterbilt 587 Deck Plates & Air Line Boxes

Frequently Asked Questions About Peterbilt 587 Deck Plates & Air Line Boxes

What are deck plates and air line boxes used for on the Peterbilt 587?

Deck plates and air line boxes are mounted on the back of the cab or behind the sleeper on the Peterbilt 587 to organize and protect the air lines and electrical connections that run to the trailer. The deck plate provides a mounting surface for gladhands and electrical sockets, while the air line box houses and shields the hose connections from road debris, moisture, and physical damage.

Will these deck plates and air line boxes fit my Peterbilt 587 without modification?

Products in this category are designed to match the factory mounting points and body lines of the Peterbilt 587, so they typically install using the existing holes and hardware locations. However, because trucks can vary slightly depending on model year, cab configuration, and prior aftermarket work, it's a good idea to compare the listed dimensions and mounting pattern to your truck before ordering.

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

Most deck plates and air line boxes for the Peterbilt 587 are constructed from stainless steel or aluminum, chosen for their resistance to rust and corrosion in outdoor, all-weather conditions. Stainless steel options often come in polished or brushed finishes for a cleaner look, while aluminum versions tend to be lighter in weight. Either material is built to withstand daily exposure to road salt, moisture, and temperature swings when properly maintained.

Do I need any special tools or professional help to install a new deck plate or air line box?

Installation generally involves basic hand tools such as wrenches and sockets, since most units bolt into existing factory mounting holes. Some installations may require disconnecting air lines and electrical connectors temporarily, so it helps to have basic mechanical experience or a qualified technician on hand, especially to ensure air line connections are properly reseated and leak-free afterward.

How do I keep my deck plate and air line box looking good and functioning properly over time?

Regular washing helps remove road salt and grime that can lead to corrosion, particularly around seams and bolt holes. For stainless steel components, a routine wipe-down with a metal-safe cleaner and polish will help maintain shine and prevent surface staining. Periodically check that mounting hardware remains tight and that air line fittings are secure and free of cracks or wear, since vibration over time can loosen connections.
