Kenworth T600 Deck Plates & Air Line Boxes

Frequently Asked Questions About Kenworth T600 Deck Plates & Air Line Boxes

What is the purpose of a deck plate and air line box on my Kenworth T600?

The deck plate is the flat panel mounted behind the cab that provides a walkable surface and mounting point for hoses, cables, and electrical lines running to the trailer. The air line box, often mounted on or near the deck plate, organizes and protects the air lines and electrical connections, keeping them secure and preventing them from being pinched or snagged during hookup and travel.

Will this deck plate or air line box fit my specific Kenworth T600?

Kenworth T600 deck plates and air line boxes can vary by model year and frame configuration, so it's important to check listed dimensions, mounting hole patterns, and any notes on year compatibility before ordering. If you're unsure whether a part matches your truck's setup, comparing your existing part's measurements or reaching out to our team with your VIN or truck details can help confirm fit.

What materials are these deck plates and air line boxes made from?

Most deck plates and air line boxes are constructed from steel or aluminum. Steel versions tend to be heavier and often painted or coated for corrosion resistance, while aluminum options are lighter weight and naturally resistant to rust. The right choice depends on whether you prioritize durability and load capacity or reduced weight and easier long-term maintenance.

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

Installation typically involves unbolting the old unit from the frame or existing mounting brackets, disconnecting air lines and electrical connectors, and transferring or reattaching those lines to the new part. Most units are designed to bolt into the existing mounting points, but having basic hand tools and someone to help support the plate during removal and installation makes the job easier, especially since these parts can be bulky.

How do I know if my current deck plate or air line box needs to be replaced?

Common signs include visible rust or corrosion that compromises structural integrity, cracked or bent plating, loose or broken mounting brackets, and air line boxes that no longer hold connections securely. If you notice lines rattling loose, physical damage from road debris, or the plate no longer sitting flush and stable, it's a good indication that a replacement is needed to maintain safe and reliable operation.
