Kenworth W900B/W900L Dash Knobs

Frequently Asked Questions About Kenworth W900B/W900L Dash Knobs

What are dash knobs used for on a Kenworth W900B/W900L?

Dash knobs are the small control knobs mounted on the dashboard that operate functions such as headlights, dimmer switches, heater and AC controls, wiper controls, and other panel-mounted switches. They are often the first thing to wear out or crack due to constant handling, so replacing them is a common and simple upgrade or repair.

Will these dash knobs fit my specific W900B or W900L model year?

Fitment can vary by model year and dash configuration, since Kenworth updated switch and knob styles over the years. Always check the listed compatible years and shaft/stem style on each product page before ordering, and compare the thread size or mounting style of your current knob to ensure a proper match.

What materials and finishes are available for these knobs?

Dash knobs are typically available in materials like chrome-plated plastic, aluminum, and durable ABS plastic. Finish options often include polished chrome, black, or wood grain styles to match or upgrade the look of your existing dash, giving you both functional and cosmetic choices.

How do I install a replacement dash knob?

Most dash knobs simply pull off or unscrew from the switch shaft they are mounted on. In many cases, you can remove the old knob by pulling straight off or loosening a small retaining screw, then press or thread the new knob into place. No special tools are typically required, but always confirm your specific knob's attachment method before starting.

Can I use these knobs to replace a cracked or worn factory knob without replacing the whole switch?

Yes, in most cases the dash knob is a separate component from the underlying switch or control mechanism. If the switch itself still works but the knob is cracked, faded, or loose, you can typically replace just the knob rather than the entire switch assembly, saving time and cost.
