Freightliner Cabover Deck Plates-Air Line Box

Frequently Asked Questions About Freightliner Cabover Deck Plates-Air Line Box

What is a deck plate and air line box used for on a Freightliner cabover?

The deck plate is the flat panel located behind the cab that provides a walking and working surface over the frame rails, while the air line box houses and protects the air and electrical lines that run between the tractor and trailer. Together, these components protect critical lines from road debris and wear while giving drivers a safer, more stable surface to stand on during hookups and inspections.

Will this deck plate and air line box fit my specific Freightliner cabover model?

Fitment can vary by model year and cab configuration, so it's important to check the listed specifications and compatible models on each product page before ordering. If you're unsure whether a part matches your truck, our customer service team can help confirm fitment using your VIN or model details prior to purchase.

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 are constructed from steel or aluminum, chosen for durability against constant exposure to road debris, moisture, and heavy foot traffic. Steel versions typically offer added strength and are often finished with a protective coating, while aluminum options provide a lighter-weight alternative with natural corrosion resistance.

Do these parts come pre-drilled, or will I need to modify them for installation?

Many replacement deck plates and air line boxes are designed to bolt on using the factory mounting locations, but some may require drilling or minor fabrication depending on the specific truck and part design. We recommend reviewing the installation notes on each listing and comparing them to your original setup before beginning the swap.

Can I install a new deck plate or air line box myself, or do I need a professional?

Installation difficulty depends on the complexity of your air and electrical line routing, but many drivers and shop technicians are able to complete the swap with basic tools and some mechanical experience. If your truck has extensive custom wiring or air line configurations, having a qualified technician handle the installation can help ensure everything is properly sealed and routed.
