Frequently Asked Questions About International 9300/9370 Deck Plates & Air Line Boxes

Will these deck plates fit my specific International 9300 or 9370 model year?

Our deck plates are designed to fit International 9300 and 9370 models from 1987 through 2007. However, there are slight variations between early models (1987-1999) and later models (2000-2007) due to frame rail spacing changes. When ordering, please verify your truck's exact year and measure the distance between your frame rails to ensure proper fitment. Most deck plates are adjustable within a range, but confirming measurements prevents installation issues.

What gauge steel are these deck plates made from, and will they hold up to daily use?

Most of our International 9300/9370 deck plates are manufactured from either 14-gauge or 16-gauge steel, with some heavy-duty options available in 12-gauge. The 16-gauge plates work well for standard applications and light air line storage, while 14-gauge or thicker is recommended for heavier use or if you plan to step on the plates regularly. All plates feature either powder coating or chrome plating for corrosion resistance, though chrome options require more maintenance in harsh winter conditions.

Do I need to drill holes in my frame to install these deck plates?

Most deck plates for the International 9300/9370 are designed to utilize existing frame holes whenever possible. However, some installations may require drilling 1-2 additional holes per side, depending on your specific truck configuration and the deck plate model chosen. Installation typically takes 1-2 hours and requires basic hand tools plus a drill with metal bits if new holes are needed. We recommend checking your frame for existing mounting points before ordering.

What's the difference between deck plates with and without air line boxes?

Standard deck plates provide a flat surface to cover the gap between your cab and sleeper, improving appearance and aerodynamics. Deck plates with integrated air line boxes include enclosed storage compartments (usually one per side) that protect your air lines, electrical connections, and glad hands from weather and road debris. The box-style plates add about 4-6 inches of depth and are ideal if your air lines are currently exposed or you want cleaner line routing.

Are these deck plates available in different finishes to match my truck?

Yes, we offer deck plates in several finishes to match your International 9300/9370. The most common options are mirror-polished stainless steel, chrome-plated steel, and black powder coat. Some models also come in brushed stainless or can be ordered unfinished for custom painting. Chrome provides the brightest shine but requires regular polishing, while stainless steel offers excellent durability with less maintenance. Black powder coat is ideal for work trucks or those seeking a subtle appearance.
