Frequently Asked Questions About Freightliner FLD SBA Frame Light Bars-Filler Panels

What years and models of Freightliner FLD trucks are these light bars and filler panels compatible with?

These light bars and filler panels are designed specifically for Freightliner FLD models with the set-back axle (SBA) configuration, typically ranging from 1989 to 2007. They fit FLD120 and FLD112 models with the standard frame width. Before ordering, verify your truck has the SBA configuration by checking if your front axle is positioned further back from the bumper compared to standard FLD models. If you're unsure, measure the distance from your bumper to the front axle or contact us with your VIN for compatibility verification.

What materials are these light bars made from, and how durable are they against rust and corrosion?

Our light bars are manufactured from either 304-grade stainless steel or heavy-duty mild steel with chrome plating, depending on the specific model you choose. Stainless steel options provide superior corrosion resistance and typically last 15-20 years with minimal maintenance. Chrome-plated steel versions offer excellent appearance but require more regular cleaning and may need re-chroming after 7-10 years in harsh climates. All mounting brackets are zinc-plated for additional rust protection.

How difficult is the installation process, and what tools or modifications are required?

Installation typically takes 2-4 hours for someone with basic mechanical skills. You'll need standard hand tools including socket wrenches, drill with metal bits, and wire crimpers for electrical connections. Most light bars bolt directly to existing frame mounting points, though some models may require drilling 2-4 additional holes. Filler panels usually snap or bolt into place without modifications. Wiring harnesses are included with plug-and-play connectors that integrate with your truck's existing electrical system. Professional installation is recommended if you're uncomfortable with electrical work.

What light configurations and finish options are available?

Light bars come in several configurations: 5-light, 7-light, and 9-light options with either round or rectangular LED or halogen lights. Finish options include mirror-polished stainless steel, standard chrome, and powder-coated black. Filler panels are available in matching finishes to create a cohesive look. LED options draw less power and last longer (50,000+ hours) compared to halogen (2,000-3,000 hours). Most customers choose LED for reliability, though halogen provides a classic appearance.

Will adding these light bars affect my truck's ground clearance or approach angle?

Light bars typically extend 6-8 inches below the frame rail, which may reduce ground clearance by 2-3 inches depending on your current setup. The SBA frame design generally provides better clearance than standard FLD models, but you should measure your current clearance before installation. For trucks frequently navigating steep driveways or off-road conditions, we offer low-profile options that extend only 4-5 inches below the frame. Filler panels do not affect ground clearance as they fill the gap between existing components.
