Frequently Asked Questions About Freightliner FL70-FL80 Light Bars & Filler Panels

What year models of FL70 and FL80 trucks are these light bars and filler panels compatible with?

Our light bars and filler panels are designed to fit Freightliner FL70 and FL80 models from 1996 to 2007. The mounting holes and dimensions are specifically engineered for these model years. If you have a pre-1996 model or a different Freightliner series, please contact our customer service team to discuss custom options or alternative solutions.

Are these light bars made from steel or aluminum, and will they rust over time?

Most of our FL70-FL80 light bars are constructed from heavy-duty steel with either a chrome-plated or powder-coated finish for corrosion resistance. Chrome options provide excellent rust protection when properly maintained, while powder-coated versions offer superior durability in harsh weather conditions. We also carry select aluminum models that are naturally rust-resistant but may be more expensive. Each product listing specifies the material and finish type.

Do I need to drill new holes for installation, or will these mount using existing holes?

The majority of our light bars and filler panels are designed as direct bolt-on replacements that utilize your truck's existing mounting points. No drilling is typically required for standard installations. However, if you're adding auxiliary lights or customizing the configuration, some drilling may be necessary. Each product includes detailed mounting instructions, and we recommend having basic hand tools and approximately 2-3 hours for installation.

What's the difference between a light bar and a filler panel, and do I need both?

A light bar is the mounting bracket that holds your auxiliary lights and typically spans across the front of your truck. A filler panel is the decorative piece that fills the gap between the bumper and grille, providing a finished appearance. While you don't always need both, many drivers prefer the complete setup for a professional look. Light bars are functional additions for mounting work lights or fog lights, while filler panels are primarily aesthetic but can also help with aerodynamics.

Will aftermarket light bars affect my truck's front-end weight distribution or void any warranties?

Our light bars typically add between 15-40 pounds to the front end, depending on the model and any lights you mount. This minimal weight addition won't significantly impact your truck's handling or weight distribution. Regarding warranties, installing aftermarket light bars or filler panels generally doesn't void your vehicle warranty, but we recommend checking with your dealer if your truck is still under warranty. These are considered cosmetic modifications that don't interfere with critical vehicle systems.
