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

What Kenworth cabover models are these light bars and filler panels compatible with?

These light bars and filler panels are designed specifically for Kenworth K100 and K100E cabover models from 1963 through 2010. The mounting points and dimensions are engineered to match the factory frame rail spacing on these trucks. Always verify your specific year and model before ordering, as some minor variations exist between early and late production years.

Are these light bars made from stainless steel or chrome-plated steel, and which option lasts longer?

We offer both 304 stainless steel and chrome-plated steel options. The 304 stainless steel light bars require minimal maintenance and resist corrosion even in harsh weather conditions, making them ideal for trucks operating in salt-heavy environments. Chrome-plated steel provides a mirror-like finish but requires regular polishing and may show pitting over time if the chrome layer is compromised. For longevity with less maintenance, stainless steel is the superior choice.

Do I need to drill any holes for installation, and what tools are required?

Most of our light bars utilize existing frame holes and require no drilling. Installation typically requires basic hand tools including socket wrenches, screwdrivers, and possibly a drill for wiring access. The mounting brackets are designed to align with factory mounting points. Complete installation usually takes 2-4 hours depending on whether you're adding lights. We recommend having a second person assist with alignment during installation.

Can I mount additional lights on these bars, and what's the weight capacity?

Yes, our light bars are pre-drilled to accept standard 2-inch and 4-inch round lights, with most bars accommodating 4-8 lights depending on the model. The bars are rated to support up to 50 pounds of evenly distributed weight, which is more than sufficient for LED or incandescent marker lights. The pre-drilled holes are spaced to comply with DOT lighting requirements for commercial vehicles.

Will these filler panels work with aftermarket bumpers or only OEM bumpers?

Our filler panels are designed to work with both OEM and most aftermarket bumpers that maintain factory mounting dimensions. They bridge the gap between the bumper and frame rails, providing a finished appearance regardless of bumper type. However, some custom or heavily modified bumpers may require minor adjustments to the filler panels for proper fitment. We recommend test-fitting before final installation.
