Frequently Asked Questions About Freightliner FLC120 Deck Plates & Air Line Boxes

What years and models of Freightliner FLC120 trucks do these deck plates fit?

Our deck plates and air line boxes are designed to fit Freightliner FLC120 models from 1988 through 2003. They're compatible with both day cab and sleeper configurations. However, we recommend double-checking your specific truck's measurements, as some custom modifications or aftermarket bumpers may affect fitment. The standard deck plate opening should measure approximately 18" x 24" for proper installation.

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

Most of our FLC120 deck plates are manufactured from 14-gauge steel (approximately 0.075" thick) with a durable powder-coated finish to resist corrosion. We also carry aluminum options that are typically 1/8" thick (0.125") for customers seeking weight savings. Steel plates generally weigh 15-20 pounds, while aluminum versions weigh about 6-8 pounds. Both materials provide excellent durability for daily use and road conditions.

Do I need to drill new holes or modify my bumper to install these deck plates?

In most cases, our deck plates are designed to use existing mounting holes in your FLC120 bumper. Installation typically requires removing 4-6 bolts from your current plate or blank cover. However, if you're converting from a solid bumper section to an air line box configuration, you may need to cut an opening. We recommend having a professional perform any cutting to ensure proper fitment and maintain bumper integrity.

What's the difference between a standard deck plate and one with integrated air line boxes?

Standard deck plates provide a flat, sealed surface to cover bumper openings and are ideal for trucks that don't require frequent trailer connections. Deck plates with integrated air line boxes feature built-in gladhand holders and storage compartments for air lines and electrical connections. These combination units keep your connections organized, protected from road debris, and easily accessible. They're especially popular with owner-operators who frequently hook and unhook trailers.

Will these deck plates work with chrome, painted, or stainless steel bumpers?

Yes, our deck plates are compatible with all bumper finishes. We offer plates in multiple finishes including chrome-plated steel, polished stainless steel, painted black, and bare steel (ready for custom painting). For the best aesthetic match, we recommend choosing a deck plate finish that complements your bumper. Chrome plates work well with chrome bumpers, while our paintable options allow you to color-match painted bumpers perfectly.
