Kenworth W900B/W900L Frame Light Bars-Filler Panel

Frequently Asked Questions About Kenworth W900B/W900L Frame Light Bars-Filler Panel

What exactly is a frame filler panel, and what does it do?

A frame filler panel is the section that mounts between the frame rails, typically below the bumper or behind the grille area, closing the gap between the frame rails and often incorporating cutouts or mounting points for lights. On the W900B and W900L, these panels help complete the front-end appearance while providing a mounting surface for marker or light bars.

Will this filler panel fit both the W900B and W900L, or are they different?

The W900B and W900L have different frame and hood configurations, so filler panels are not always interchangeable between the two models. Always check the listed application details and confirm your truck's specific model and frame width before ordering to ensure proper fit.

What material are these panels made from, and what finish options are available?

Frame light bars and filler panels are commonly offered in stainless steel or aluminum. Stainless steel options are typically available in polished or plain finishes, while aluminum panels may come in a brushed or diamond plate finish. Choose based on the look you want and how the panel will hold up to road exposure over time.

Does the panel come with the lights and wiring included, or do I need to buy those separately?

This varies by product. Some filler panels are sold pre-drilled with light bars and wiring harnesses already installed, while others are sold as a blank panel or with cutouts only, requiring you to source and wire the lights separately. Check the product description carefully to see exactly what is included before you order.

What's involved in installing a frame filler panel, and do I need any special tools?

Installation generally involves removing the old panel or fasteners, positioning the new panel between the frame rails, and securing it with bolts or brackets at the existing mounting points. If the panel includes lights, you will also need to connect the wiring to your truck's existing light circuit. Basic hand tools are usually sufficient, but if your panel isn't pre-wired, some electrical know-how or a helper familiar with truck wiring will make the job easier.
