Freightliner Cascadia 113/125 Light Bars-Panels

Frequently Asked Questions About Freightliner Cascadia 113/125 Light Bars-Panels

What exactly are frame light bars and filler panels used for on a Cascadia?

These components mount along the frame rails, typically between the cab and fuel tanks or along the lower chassis, to fill open gaps left by the truck's frame design. They provide a mounting surface for auxiliary lighting, such as marker lights or LED strips, while also giving the underside of the truck a cleaner, more finished appearance.

Will a light bar or filler panel fit both the Cascadia 113 and 125 models?

Fitment can vary between the 113 and 125 wheelbase configurations, as well as by production year, since frame spacing and mounting points are not always identical. Always check the listed vehicle compatibility on each product page and compare it against your truck's VIN or existing frame dimensions before ordering.

What materials and finishes are these panels available in?

Most light bars and filler panels are constructed from stainless steel or aluminum. Stainless versions are commonly available in polished, brushed, or diamond plate finishes, offering durability and corrosion resistance for long-term use in varying weather conditions. Aluminum options tend to be lighter but still hold up well against everyday wear.

Do these panels come pre-drilled for lights, and are the lights included?

Many panels come pre-drilled with mounting holes sized for standard round or oval lights, but this varies by product, so check the specific listing for hole count and spacing. In most cases, the lights themselves are sold separately unless the listing specifically states a light kit is included.

How difficult is it to install a frame light bar or filler panel myself?

Installation difficulty depends on the specific panel and mounting location, but most are designed to bolt into existing frame holes or brackets already present on the truck, making them straightforward for anyone comfortable with basic hand tools. If wiring for lights is involved, some basic electrical know-how will help ensure a clean, weatherproof connection.
