International PayStar 5000 Deck Plates-Air Box

Frequently Asked Questions About International PayStar 5000 Deck Plates-Air Box

What is a deck plate/air line box used for on the International PayStar 5000?

The deck plate and air line box assembly sits behind the cab, providing a mounting surface and protective housing for the air, electrical, and hydraulic lines that run between the tractor and trailer. It also serves as a walkway or step surface for accessing components behind the cab, so it needs to be both structurally sound and slip-resistant.

Will this deck plate/air box fit my specific PayStar 5000 model year?

Fitment can vary depending on the model year and frame configuration of your PayStar 5000, since International made changes to cab and chassis dimensions over different production runs. Always check the listed year range and part specifications before ordering, and compare mounting hole patterns and overall dimensions to your existing unit if possible. If you are unsure, reach out to our parts team with your VIN or existing part number for confirmation.

What material are these deck plates and air boxes made from, and how durable are they?

Most deck plates and air line boxes in this category are constructed from steel or aluminum, chosen for their strength and resistance to the vibration, road debris, and weather exposure common in this mounting location. Steel versions typically come with a durable finish to resist corrosion, while aluminum options offer a lighter-weight alternative with natural corrosion resistance. Check each product listing for the specific material and finish used.

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

Installation generally involves removing the old unit, transferring or reconnecting air and electrical lines, and bolting the new deck plate or box into place using the existing mounting points. Many experienced truck owners and shop technicians can handle this with basic tools, but because the assembly involves air lines and wiring that affect braking and lighting systems, it is important to work carefully and double check all connections before returning the truck to service. If you are not confident working with air brake lines, having a qualified technician complete the install is a safer choice.

Does the air box include pre-drilled holes or fittings for air lines and electrical connections?

Many air boxes come with cutouts or knockouts for common air line and electrical connections, but the exact configuration can differ by manufacturer and part number. Review the product description and images closely to confirm it matches the routing and fitting setup on your truck, and be prepared to do some minor drilling or fitting adjustments depending on your specific line configuration.
