Frequently Asked Questions About Freightliner FL70-FL80 Deck Plates & Air Line Boxes

What years and models are these deck plates compatible with?

These deck plates and air line boxes are designed specifically for Freightliner FL70 and FL80 models from 1995 through 2010. They fit both standard and extended cab configurations. Before ordering, verify your truck's exact year and model as mounting hole patterns changed slightly between 1995-2002 and 2003-2010 models. Most products will specify which year range they cover in the product description.

Are these deck plates made of aluminum or stainless steel, and which is better?

Both materials are available depending on the specific product. Aluminum deck plates (typically 3/16" thick) are lighter weight and more affordable, making them ideal for most applications. They resist corrosion well but may show scratches over time. Stainless steel options (usually 16-gauge) offer superior durability and maintain their appearance longer, especially in harsh weather conditions or heavy salt exposure. Choose stainless if you prioritize longevity and appearance, or aluminum for cost-effectiveness and easier handling during installation.

How difficult is the installation process, and what tools do I need?

Installation typically takes 2-3 hours for someone with basic mechanical skills. You'll need a drill with metal bits (5/16" and 3/8" typically), a center punch, measuring tape, and basic hand tools. Most deck plates require drilling 4-8 mounting holes. The main challenges customers report are ensuring proper alignment before drilling and accessing tight spaces behind the cab. We recommend having a helper to hold the plate in position while marking holes. Some customers find it easier to remove the bumper for installation, though it's not always necessary.

What's the difference between plain, tread plate, and polished finishes?

Plain finish deck plates have a smooth, brushed appearance that hides minor scratches well and requires minimal maintenance. Tread plate (diamond plate) options provide better grip when stepping on them and add a rugged appearance, though they can collect more dirt in the grooves. Polished finishes offer the shiniest appearance but require regular cleaning and polishing to maintain their mirror-like look. Consider your maintenance preferences and how often the deck plate will be stepped on when choosing a finish.

Will these deck plates work with aftermarket bumpers or air brake configurations?

Most deck plates are designed to work with factory bumper configurations, but compatibility with aftermarket bumpers varies. Measure the available space between your bumper and cab before ordering. Standard deck plates typically measure 18-24 inches wide. For trucks with relocated air lines or custom brake configurations, you may need to modify mounting positions or choose boxes with adjustable gladhand holders.
