Kenworth T700 Frame Light Bars & Filler Panels

Frequently Asked Questions About Kenworth T700 Frame Light Bars & Filler Panels

What are frame light bars and filler panels used for on a Kenworth T700?

These components mount along the truck's frame rail, typically between the cab and rear wheels or in the fuel tank area, to fill open gaps and provide a clean, finished appearance. Many frame light bars also include cutouts or built-in housings for auxiliary lighting, allowing you to add marker lights or accent lighting while covering exposed frame sections.

Will this fit my specific Kenworth T700 configuration?

Fitment can vary depending on your truck's wheelbase, fuel tank size, and frame rail spacing, since the T700 was built with several different configurations. Before ordering, check the listed specifications against your truck's measurements, and reach out to our team with your VIN or frame dimensions if you're unsure -- we're happy to help confirm the correct part.

What materials and finishes are these panels available in?

Frame light bars and filler panels are commonly offered in stainless steel or aluminum, with finishes ranging from brushed or polished stainless to painted or plain aluminum. Stainless steel tends to hold up well against corrosion and road grime, while aluminum options can offer a lighter-weight alternative. Choose a finish that matches the rest of your truck's trim for a consistent look.

Do these panels come with lights included, or do I need to buy them separately?

This depends on the specific product. Some frame light bars are sold pre-drilled or with light housings included, while others are plain filler panels with no lighting provisions. Be sure to check the product description closely to know whether lights, grommets, or wiring are included or need to be purchased separately.

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

Installation difficulty varies by product, but most panels are designed to bolt or mount directly to existing frame holes or brackets, making the process straightforward for anyone comfortable with basic hand tools. If the panel includes lighting, you'll also need to run wiring to a power source and ground, so budget extra time for that step. Always test fit the panel before final tightening to make sure all mounting points line up correctly.
