Mack CH/CHN/CHU Light Bar-Filler Panel

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

What exactly is a light bar-filler panel, and what does it do?

A light bar-filler panel is the section that mounts between the bumper and the grille/hood area on Mack CH, CHN, and CHU trucks, typically housing marker lights, turn signals, or auxiliary lighting. It closes the gap left by the frame or bumper design while also providing a mounting location for lighting components, giving the front end a finished, factory-style appearance.

Will this filler panel fit my specific Mack CH, CHN, or CHU model?

Fitment can vary slightly by model year and cab configuration, even within the CH, CHN, and CHU lineup. Before ordering, check the listed specifications and compare them to your truck's existing panel or frame dimensions. If you're unsure, it's a good idea to have your VIN or model year on hand and reach out to our team to confirm the correct fit before purchasing.

What materials are these panels made from, and how do they hold up?

Filler panels in this category are commonly available in steel or stainless steel, with some finished in chrome or a painted/primed surface for a more budget-friendly option. Stainless and chrome panels tend to resist corrosion and road grime better over time, which matters given their location near the front of the truck where they're exposed to debris, salt, and moisture.

Do these panels come pre-drilled for lights, or will I need to do additional fabrication?

Most panels in this category are pre-drilled or pre-cut to accept standard light sizes, but exact hole placement and light compatibility can differ between manufacturers. Check the product description for details on light cutout sizes and count so you know whether your existing lights will fit or if you'll need to purchase new ones designed for that panel.

Is installation something I can do myself, or does it require a professional shop?

Many customers install these panels themselves with basic hand tools, especially if the panel is a direct bolt-on replacement for the original. However, if wiring for lights is involved, or if the old panel is rusted, bent, or requires cutting, it may be easier and safer to have a shop handle the install. Always disconnect any electrical connections before removing the old panel and take note of how the wiring is routed for reference.
