Frequently Asked Questions About Mack CH/CHN/CHU Light Bar-Filler Panels

Will these light bars and filler panels fit my specific Mack CH model year?

Our light bars and filler panels are designed to fit Mack CH, CHN, and CHU models from 1988 through 2007. However, there are some variations between early and late model years. Pre-2000 models may have slightly different mounting hole patterns compared to 2000-2007 models. We recommend checking your existing mounting points or contacting our support team with your VIN to ensure proper fitment before ordering.

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

Most of our Mack CH light bars are constructed from either 304 stainless steel or heavy-duty aluminum, depending on the specific product. Stainless steel options offer superior corrosion resistance and typically come with a mirror polish or brushed finish. Aluminum bars are powder-coated for durability and weather resistance. Both materials are designed to withstand harsh road conditions, though stainless steel provides the longest-lasting rust protection.

Do I need to drill new holes or modify my bumper for installation?

In most cases, our light bars and filler panels are designed to use existing factory mounting points on your Mack CH bumper. However, some aftermarket bumpers or custom setups may require drilling. The installation typically involves removing 4-6 bolts from your current setup and bolting on the new components. We include detailed instructions with each product, and installation usually takes 30-60 minutes with basic hand tools.

What's the difference between a light bar and a filler panel?

A light bar includes pre-drilled holes and mounting provisions for auxiliary lights, typically accommodating 4-7 lights depending on the model. Filler panels are solid pieces without light mounting holes, designed to create a clean, finished look when you don't need additional lighting. Both serve to fill the gap between your bumper and grille, but your choice depends on whether you want to add extra lights to your truck.

Can I mount any type of lights on these light bars?

Our light bars are pre-drilled to accept standard 4-inch round lights, which are the most common size for commercial trucks. Some models also accommodate 2-inch marker lights. The holes are typically spaced to meet DOT regulations for auxiliary lighting. While you can mount LED, halogen, or strobe lights, ensure your chosen lights don't exceed the weight capacity of the bar (usually 5-7 pounds per light) and that your electrical system can handle the additional load.
