Frequently Asked Questions About International ProStar Frame Light Bars & Panels

What years and models of International ProStar are these light bars compatible with?

Our frame light bars and panels are designed to fit International ProStar models from 2008 through 2017. These parts are specifically engineered for the ProStar's frame dimensions and mounting points. If you have a 2018 or newer model, please contact our customer service team as the frame design changed slightly and may require different mounting hardware or modifications.

Are these light bars made of steel or aluminum, and will they rust?

Most of our ProStar frame light bars are constructed from heavy-duty steel with either a chrome-plated or powder-coated finish for corrosion resistance. Chrome options provide excellent rust protection when properly maintained, while powder-coated versions offer superior durability in harsh weather conditions. We also carry select aluminum models that are naturally rust-resistant but typically cost more. Each product listing specifies the material and finish type.

Do I need to drill holes or modify my truck frame to install these light bars?

The majority of our frame light bars are designed as no-drill installations that utilize existing frame holes and mounting points on your ProStar. Installation typically requires basic hand tools and takes 1-2 hours per side. Some custom or aftermarket options may require drilling, but this will be clearly noted in the product description. We recommend having a second person assist with alignment during installation.

Can I mount additional lights on these bars, and what's the weight capacity?

Yes, our frame light bars are designed to support additional LED or halogen lights. Most bars can safely support 15-25 pounds of additional lighting per side, depending on the specific model. Pre-drilled mounting holes are typically included for standard 4-inch and 6-inch round lights. Always ensure your total light setup doesn't exceed your state's width restrictions for commercial vehicles.

What's the difference between light bars and filler panels, and do I need both?

Light bars are functional mounting brackets that extend from your frame and allow you to add auxiliary lighting for improved visibility and safety. Filler panels are decorative pieces that cover gaps between the frame and bumper for a cleaner, more finished appearance. While you don't need both, many drivers choose to install them together for the best combination of functionality and aesthetics. Filler panels can be installed independently if you only want the visual upgrade.
