Frequently Asked Questions About GMC Brigadier Light Bar-Filler Panels

What years and models of GMC Brigadier trucks are these light bars and filler panels compatible with?

Our GMC Brigadier light bars and filler panels are designed to fit 1988-2002 GMC Brigadier models. However, compatibility can vary based on specific cab configurations and whether your truck has factory mounting points. We recommend checking your truck's VIN and measuring the mounting area before ordering. If you're unsure about fitment, contact our customer service team with your truck's year, model, and any modifications for personalized assistance.

Are these light bars made of steel or aluminum, and how do they hold up against rust and corrosion?

Most of our GMC Brigadier light bars are constructed from heavy-duty steel with either a chrome-plated or powder-coated finish for maximum durability. Chrome options provide excellent corrosion resistance and a classic look, while powder-coated versions offer superior chip resistance and come in various colors including black and white. For trucks operating in high-salt environments, we recommend regular cleaning and inspection of mounting points to maintain the finish integrity.

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

Many of our light bars are designed to utilize factory mounting points when available, but some installations may require drilling depending on your truck's configuration and previous modifications. Each product includes detailed mounting instructions specifying whether drilling is necessary. Most installations require basic hand tools, though some customers find an impact driver helpful for stubborn bolts. Installation typically takes 2-4 hours for those with moderate mechanical experience.

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

Light bars are functional mounting systems that hold auxiliary lights above your cab, while filler panels are cosmetic pieces that cover gaps between the cab and sleeper or fill unused light bar mounting areas for a cleaner appearance. Whether you need both depends on your truck's configuration and your goals. If you're adding lights, you'll need a light bar. If you have gaps or unused mounting points you want to cover, filler panels provide a finished look. Many drivers choose both for a complete, professional appearance.

Can I mount any type of auxiliary lights on these light bars, and what's the weight capacity?

Our GMC Brigadier light bars are engineered to support most standard auxiliary truck lights, including LED light bars, round spot/flood lights, and beacon lights. Weight capacity typically ranges from 50-100 pounds depending on the specific model, which accommodates most commercial lighting setups. The bars include pre-drilled holes matching common light mounting patterns, though some custom drilling may be needed for specialty lights. Always ensure your total light weight stays within the bar's rated capacity to prevent sagging or structural issues.
