Frequently Asked Questions About Freightliner Classic Deck Plates & Air Line Boxes

Will these deck plates fit my specific year Freightliner Classic model?

Our deck plates are designed to fit Freightliner Classic models from 1990 through 2007. However, there are slight variations between early models (1990-1999) and later models (2000-2007) due to changes in frame spacing and mounting hole patterns. We recommend checking your existing deck plate measurements or contacting our support team with your VIN to ensure proper fitment. Most universal deck plates will require minor drilling adjustments for pre-2000 models.

What material options are available and which holds up best against road salt and weather?

We offer deck plates in three primary materials: 304 stainless steel, aluminum diamond plate, and chrome-plated steel. For maximum durability against road salt and harsh weather, 304 stainless steel is the best choice as it won't rust or corrode. Aluminum diamond plate is lightweight and corrosion-resistant but may show oxidation over time. Chrome-plated steel looks great initially but requires regular maintenance to prevent rust, especially in winter driving conditions. Most professional drivers choose stainless steel for long-term value.

Do I need to remove my fuel tanks to install deck plates and air line boxes?

In most cases, you do not need to remove fuel tanks for deck plate installation. The deck plates can typically be installed by loosening the tank straps and sliding them into position. However, for air line box installation, you may need to temporarily loosen or reposition the tanks depending on your specific setup. The entire installation usually takes 2-4 hours with basic hand tools. We include detailed instructions with diagrams for DIY installation.

What's the difference between OEM-style and aftermarket deck plates?

OEM-style deck plates match the original factory specifications with exact mounting holes and dimensions, making them direct bolt-on replacements. Aftermarket options often feature upgraded materials, additional chrome accents, or LED light cutouts not found on factory plates. While aftermarket plates may require minor modifications during installation, they typically offer better corrosion resistance and aesthetic options. Both types maintain the same basic functionality for protecting air lines and wiring.

Can I add LED lights to my deck plates, and will they work with my existing wiring?

Yes, many of our deck plates come pre-drilled for standard 2-inch or 4-inch LED marker lights. These lights can be wired into your existing clearance light circuit using standard 2-wire connections. Some deck plates feature integrated LED strips that require a simple 12V connection. We recommend using weatherproof connectors and applying dielectric grease to all connections. Always verify your truck's electrical capacity can handle additional lights - most Freightliner Classics can support 6-8 additional LED markers without issue.
