Frequently Asked Questions About International ProStar Deck Plates & Air Line Boxes

What material are these deck plates made from, and will they rust or corrode?

Most International ProStar deck plates are manufactured from either 16-gauge stainless steel or heavy-duty aluminum. Stainless steel options offer superior corrosion resistance and typically come in polished or brushed finishes. Aluminum deck plates are lighter weight and naturally resist corrosion but may show wear patterns over time. Both materials are designed to withstand road salt, weather exposure, and daily commercial use. For maximum longevity in harsh climates, we recommend stainless steel with a polished finish.

Will these deck plates fit my specific ProStar model year?

These deck plates are designed to fit International ProStar models from 2008 through 2017. The mounting holes and dimensions are consistent across these model years. However, trucks with aftermarket bumpers or custom modifications may require additional fitting. Pre-2008 International models use different mounting configurations and are not compatible. Always verify your truck's VIN and model year before ordering, and contact our support team if you have a ProStar with any front-end modifications.

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

No drilling is required for standard installations on factory ProStar bumpers. These deck plates use existing mounting points and come with all necessary hardware including bolts, washers, and spacers. Installation typically takes 30-45 minutes per side using basic hand tools. Some customers report needing to slightly enlarge existing holes on older models due to corrosion buildup. If your truck has an aftermarket bumper, custom drilling may be necessary - we recommend test-fitting before final installation.

What styles and finishes are available, and which holds up best?

Deck plates come in several styles including smooth, diamond plate, and louvered designs. Finish options include mirror polish, brushed stainless, and powder-coated aluminum. Based on customer feedback, mirror-polished stainless steel requires more frequent cleaning but maintains its appearance longest when properly maintained. Brushed finishes hide minor scratches better and need less frequent polishing. Diamond plate patterns offer additional traction but can trap dirt in the grooves. For easiest maintenance, most drivers prefer brushed stainless steel.

Can I mount additional accessories like lights or air horns to these deck plates?

Yes, most deck plates can accommodate additional accessories, but weight limits vary by material and thickness. Stainless steel plates handle heavier accessories better than aluminum. Many plates come pre-drilled with common light mounting patterns, while others require custom drilling. When adding accessories, ensure the combined weight does not exceed 25 pounds per plate to prevent sagging. Use stainless steel hardware for all accessory mounting to prevent galvanic corrosion between different metals.
