Frequently Asked Questions About Peterbilt 362 Deck Plates & Air Line Boxes

What years and models of Peterbilt 362 are these deck plates compatible with?

Our deck plates and air line boxes are designed to fit Peterbilt 362 models from 1980 through 1986. These parts are specifically engineered for the 362's unique cab-over-engine design and mounting points. While some components may physically fit other Peterbilt models like the 352 or 372, we recommend verifying exact measurements and mounting hole patterns before ordering for non-362 applications.

Are these deck plates made from aluminum or steel, and how thick is the material?

We offer deck plates in both materials to suit different needs. Our aluminum deck plates are typically 1/8" (3.175mm) thick diamond plate aluminum, providing excellent corrosion resistance while keeping weight down. Steel options are usually 14-gauge (0.075") or 16-gauge (0.060") thickness, offering superior strength for heavy-duty applications. The material type and thickness are listed in each product's specifications - aluminum is ideal for weight-conscious builds, while steel provides maximum durability for severe service conditions.

Do I need to drill new holes for installation, or will these mount to existing factory locations?

Most of our deck plates are designed as direct bolt-on replacements that utilize factory mounting points. However, some custom or aftermarket air line box configurations may require drilling 2-4 additional holes. Each product listing specifies whether drilling is required. For bolt-on applications, you'll typically need standard 3/8" or 1/2" bolts with lock washers. We recommend test-fitting before final installation to ensure proper alignment with your specific truck's configuration.

What finishes are available, and how do they hold up to road salt and weather?

Our deck plates come in several finish options: mill finish aluminum (unfinished), polished aluminum, powder-coated steel (typically black or custom colors), and chrome-plated steel. Mill finish aluminum naturally develops a protective oxide layer but may show water spots. Polished aluminum requires regular maintenance to maintain shine. Powder-coated finishes offer excellent protection against rust and UV damage when properly maintained. Chrome options provide the best corrosion resistance for steel plates but are more expensive. For trucks operating in heavy salt environments, we recommend aluminum or properly sealed powder-coated options.

Can I install these myself, and what tools will I need?

Yes, most deck plate installations can be completed by someone with basic mechanical skills in 1-2 hours. You'll need: a socket set (typically 9/16" and 1/2"), drill with metal bits if new holes are required, center punch for marking, measuring tape, and safety equipment. Some installations may require removing air lines or other components for access. The most challenging part is usually accessing mounting bolts behind the cab - having a helper and using extensions or swivel sockets makes the job much easier. Professional installation typically runs $100-200 if you prefer to have a shop handle it.
