Frequently Asked Questions About International S1700-S1900 Frame Light Bar-Panels

Will these light bars fit my specific International S-Series truck model and year?

These frame light bars are designed specifically for International S1700 through S1900 series trucks manufactured from 1979 to 2001. They mount directly to the frame rails behind the bumper. However, trucks with aftermarket modifications, custom suspensions, or non-standard bumpers may require additional fitting adjustments. We recommend measuring your frame rail spacing before ordering to ensure proper fitment.

What material are these light bars made from, and will they rust?

Most frame light bars in this category are constructed from heavy-duty steel with either a chrome-plated or powder-coated finish. Chrome options provide excellent corrosion resistance but require regular cleaning to maintain their shine. Powder-coated versions offer superior chip and rust resistance, especially in harsh weather conditions. For maximum longevity, we recommend applying a rust preventative to mounting points during installation.

Do I need to drill holes or modify my truck frame for installation?

Installation typically requires drilling mounting holes into your truck's frame rails. Most light bars come with template guides or pre-marked drilling points. You'll need a quality drill with metal bits, mounting hardware (usually included), and basic hand tools. Professional installation is recommended if you're uncomfortable drilling into your frame. Some models may utilize existing frame holes, but this varies by truck configuration.

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

Yes, these light bars are designed to support auxiliary lighting such as fog lights, driving lights, or LED light bars. Most models can safely support 50-75 pounds of evenly distributed weight. Pre-drilled mounting tabs are typically included for standard light sizes. Always verify the specific weight rating for your chosen model and ensure proper weight distribution to prevent frame stress.

What's the difference between light bars and filler panels in this category?

Light bars are structural mounting systems that attach to your frame and provide mounting points for auxiliary lights. Filler panels are decorative pieces that fill the gap between your bumper and grille, creating a finished appearance. Some products combine both functions. Light bars focus on functionality and light mounting, while filler panels are primarily aesthetic but may include small light mounting provisions.
