Frequently Asked Questions About Kenworth T660 Frame Light Bars & Filler Panels

What years and models of the Kenworth T660 are these frame light bars and filler panels compatible with?

Our frame light bars and filler panels are designed to fit Kenworth T660 models from 2008 to 2017. These parts are specifically engineered for the T660's frame dimensions and mounting points. If you have a different Kenworth model like the T680 or W900, these parts will not fit properly due to different frame specifications and mounting locations.

What materials are these light bars and filler panels made from, and how durable are they?

Most of our T660 frame light bars are constructed from either 16-gauge steel or heavy-duty aluminum, depending on the specific product. Steel options come with a powder-coated or chrome-plated finish for corrosion resistance, while aluminum versions are naturally rust-resistant. Filler panels are typically made from ABS plastic or aluminum. All materials are DOT-approved and designed to withstand road debris, weather conditions, and the vibrations common in commercial trucking applications.

Do I need to drill holes or make modifications to install these parts on my T660?

Most of our frame light bars and filler panels are designed as direct bolt-on replacements using existing factory mounting holes on your T660 frame. However, some custom light bar configurations may require drilling additional holes for light mounting or wiring access. We recommend checking the specific product description or contacting us before purchase if you want a completely drill-free installation. Basic hand tools and approximately 1-2 hours are typically needed for installation.

What finish options are available, and which one holds up best against rust and corrosion?

We offer three main finish options: chrome-plated steel, powder-coated steel (available in black or custom colors), and polished aluminum. For maximum corrosion resistance, polished aluminum is the best choice as it won't rust. Chrome-plated options provide excellent appearance but require regular maintenance to prevent pitting. Powder-coated finishes offer good durability and are ideal for drivers who prefer a matte or colored appearance while still providing solid rust protection.

Will these light bars work with my existing lights, or do I need to purchase new ones?

Our frame light bars come with pre-drilled holes that accommodate standard 4-inch round LED or incandescent lights. Most T660 OEM lights will fit directly into these mounting holes. However, the spacing and number of light positions may vary between different light bar models. We offer both light bar only options and complete kits that include matching LED lights. Check the product specifications for the exact number and spacing of light mounting positions to ensure compatibility with your current setup.
