Frequently Asked Questions About International 9900/i/ix Frame Light Bars & Panels

What years and models of International 9900 trucks are these light bars compatible with?

Our frame light bars and panels are designed to fit International 9900, 9900i, and 9900ix models from 1999 through 2017. However, compatibility can vary based on your specific truck configuration, particularly if you have aftermarket bumpers or custom modifications. We recommend checking your truck's VIN and measuring your existing bumper mounting points before ordering. If you're unsure about fitment, our customer service team can help verify compatibility with your specific year and model.

Are these light bars made from stainless steel or chrome-plated steel, and how durable are they?

We offer both 304 stainless steel and heavy-duty chrome-plated steel options. The stainless steel bars feature a mirror-polished finish that resists rust and corrosion without requiring frequent maintenance. Chrome-plated options use 14-gauge steel with a triple-chrome plating process for durability, though they may require periodic polishing to maintain their shine. Both materials are designed to withstand road conditions, but stainless steel typically offers better long-term resistance to pitting and weathering, especially in areas with heavy salt use.

What's involved in the installation process, and will I need to drill new holes?

Most of our light bars are designed as bolt-on replacements that use existing frame mounting points, so drilling is typically not required for standard installations. Installation usually takes 2-4 hours depending on your experience level. You'll need basic hand tools including socket wrenches, and we recommend having a helper due to the weight of some bars (ranging from 35-65 pounds). All necessary mounting hardware is included. Some customers choose to add extra lights, which may require drilling and wiring work.

What's the difference between light bars with vertical slots versus round holes for lights?

Vertical slot designs accommodate standard 2-inch round LED or incandescent lights and offer more flexibility in light positioning and spacing. Round hole versions provide a cleaner, more uniform appearance but limit you to specific light placements. Vertical slots are generally more popular because they allow you to adjust light spacing and add or remove lights as needed. Both styles support the same types of lights, and the choice primarily comes down to your aesthetic preference and how much customization flexibility you want.

Can I install these light bars if I have an aftermarket bumper or air dam?

Compatibility with aftermarket bumpers varies significantly. These light bars are designed to work with OEM bumper configurations, so aftermarket bumpers may require modifications or custom brackets. Low-riding air dams often interfere with light bar installation and may need to be trimmed or replaced with a compatible style. Before ordering, measure the clearance between your bumper and frame rails, and check that mounting points align. We offer some universal mounting brackets that can help with non-standard installations, but custom fabrication may be necessary in some cases.
