Frequently Asked Questions About Mack CV/GU Truck Deck Plates & Air Line Boxes

What are the exact model years and configurations these deck plates fit?

These deck plates and air line boxes are specifically designed for Mack CV (formerly Vision) and GU (formerly Granite) models from 2000 to present. They fit both single and tandem axle configurations. For CV models, they're compatible with both the standard 113" BBC and extended 123" BBC versions. Please note that some minor modifications may be required for trucks with aftermarket exhaust systems or custom frame modifications.

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

Most deck plates in this category are manufactured from either 3/16" diamond plate aluminum or 14-gauge steel with a powder-coated finish. Aluminum options typically weigh 40-60% less than steel alternatives while providing excellent corrosion resistance. Steel versions offer superior strength for heavy-duty applications but require periodic maintenance to prevent rust. The material type and thickness are listed in each product's specifications.

Do I need to drill holes or make modifications to install these deck plates?

Installation requirements vary by product. Most deck plates are designed to utilize existing frame holes and mounting points, requiring no drilling. However, some universal-fit options may require drilling 2-4 mounting holes. Air line boxes typically mount using existing bolt patterns behind the cab. We recommend having basic hand tools, including a drill with metal bits, socket set, and measuring tape. Installation typically takes 1-2 hours per side.

Will these deck plates work with my existing mud flaps and fuel tank straps?

Yes, these deck plates are engineered to work with OEM mud flap hangers and standard fuel tank configurations. The plates feature cutouts and mounting provisions that accommodate factory fuel tank straps and brackets. For trucks with aftermarket oversized fuel tanks or custom mounting systems, you may need to modify the deck plate or use extended mounting hardware, which we can help you source.

What's the difference between polished, brushed, and powder-coated finishes?

Polished finishes provide a mirror-like chrome appearance but require regular maintenance with aluminum polish to maintain their shine. Brushed finishes offer a satin appearance that hides minor scratches and requires less maintenance. Powder-coated options (available in black or custom colors) provide the best protection against corrosion and stone chips but can't be polished if scratched. Consider your maintenance preferences and aesthetic goals when choosing a finish.
