Frequently Asked Questions About Peterbilt 352 Frame Light Bars & Filler Panels

Will these light bars fit my specific year Peterbilt 352?

Our frame light bars and filler panels are designed to fit Peterbilt 352 models from 1969 through 1987. However, there were minor frame variations during production years. Models from 1969-1979 typically have standard mounting hole patterns, while 1980-1987 models may require slight modifications to mounting brackets. We recommend checking your frame rail measurements before ordering, or contact our technical support team with your VIN for exact fitment verification.

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

Our light bars are manufactured from either 304 stainless steel or heavy-duty chrome-plated steel, depending on the specific product you select. The stainless steel options provide superior corrosion resistance and require minimal maintenance. Chrome-plated versions feature triple-layer chrome plating over steel for durability but may require periodic polishing and care to prevent surface rust, especially in harsh weather conditions or road salt exposure.

Do I need to drill holes in my frame to install these light bars?

Most of our Peterbilt 352 light bars utilize existing frame holes and mounting points, requiring no drilling for standard installations. The mounting brackets are designed to align with factory bolt patterns. However, if you're adding lights in non-standard positions or your truck has been modified, some drilling may be necessary. Each product includes detailed installation instructions specifying exact mounting requirements, and we provide templates for any necessary modifications.

Can I install these light bars myself, or do I need professional help?

Installation typically takes 2-4 hours for someone with basic mechanical skills and standard tools. You'll need basic hand tools, including socket wrenches, screwdrivers, and potentially a drill if adding custom light positions. The most challenging aspect is usually the wiring for the lights, which requires basic electrical knowledge to connect to your truck's existing electrical system. Many customers successfully complete the installation themselves, but we recommend professional installation if you're uncomfortable with electrical work or heavy component handling.

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

Light bars are mounting brackets designed to hold auxiliary lights along your frame rails, while filler panels are decorative pieces that cover gaps between lights or fill unused mounting spaces for a clean, finished appearance. Whether you need both depends on your setup - if you're mounting lights across the entire frame length, you'll primarily need light bars. If you want a professional look with evenly spaced lights, filler panels help create uniform spacing and hide any gaps. Many customers purchase combination sets for the most polished appearance.
