Frequently Asked Questions About Freightliner FLC112 Deck Plates & Air Line Boxes

What year models of Freightliner FLC112 trucks are these deck plates compatible with?

Our deck plates and air line boxes are designed to fit Freightliner FLC112 models from 1984 through 2003. However, we recommend verifying your specific truck's measurements before ordering, as some custom configurations may have variations. The standard mounting hole patterns typically match trucks with factory bumpers, but aftermarket modifications may require adjustment during installation.

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

Most of our FLC112 deck plates are constructed from either 14-gauge steel (approximately 0.075 inches thick) or 3/16-inch aluminum, depending on the specific model you choose. Steel options come with a powder-coated finish for corrosion resistance, while aluminum plates are naturally rust-resistant. Both materials are durable enough for daily commercial use and can support standard air line connections and electrical components.

Do I need to drill new holes to install these deck plates, or will they use existing mounting points?

The majority of our deck plates are designed to utilize existing factory mounting holes on your FLC112 bumper. However, some installations may require drilling 2-4 additional holes, particularly if you're adding air line boxes or if your truck has non-standard bumper configurations. We include template guides with most products to ensure accurate hole placement. Basic hand tools and a standard drill with metal bits are typically all that's needed.

What's the difference between a deck plate with integrated air line boxes versus separate components?

Integrated units combine the deck plate and air line boxes into one piece, offering a cleaner appearance and typically easier installation with fewer mounting points. Separate components provide more flexibility in positioning and are often preferred by drivers who need specific air line configurations or want to add boxes to existing deck plates. Integrated units generally cost 15-20% more but save installation time and provide a more professional finished appearance.

Will these deck plates work with both set-forward and set-back axle configurations?

Yes, our deck plates are compatible with both set-forward and set-back axle FLC112 configurations. The mounting design accounts for the different bumper positions. However, the air line length and routing may need adjustment based on your specific setup. Set-back axle trucks may require longer air lines (typically 12-15 inches versus standard 8-10 inches) to reach from the deck plate boxes to the glad hands behind the cab.
