Frequently Asked Questions About Semi-Truck Universal Dash Knobs
Will these universal dash knobs fit my specific truck model and year?
Our universal dash knobs are designed to fit most semi-trucks including Peterbilt, Kenworth, Freightliner, Mack, Volvo, and International models from the 1980s to present. They feature standard thread sizes of 1/4"-20, 5/16"-18, and 3/8"-16 which match 95% of OEM dash control stems. However, we recommend checking your existing knob's thread size before ordering. Simply remove your current knob and measure the stem diameter or test with a standard bolt to confirm compatibility.
What materials are these dash knobs made from, and how long will they last?
Our dash knobs are manufactured from either heavy-duty ABS plastic with UV inhibitors or machined aluminum, depending on the style you choose. The plastic knobs are impact-resistant and won't crack or fade for 5-7 years under normal use. Aluminum knobs feature anodized finishes that resist corrosion and wear. Both materials are significantly more durable than factory plastic knobs that often become brittle and break within 2-3 years.
How difficult is it to install these knobs, and what tools do I need?
Installation is straightforward and typically takes less than 5 minutes per knob. Most knobs simply thread onto your existing control stems by hand - no tools required. For set-screw style knobs, you'll need a small Allen wrench (usually included). Some older trucks may require gentle prying to remove stuck factory knobs. We recommend using a plastic trim tool to avoid dashboard damage. No drilling, cutting, or modifications are needed.
What styles and finishes are available to match my truck's interior?
We offer dash knobs in chrome, black, brushed aluminum, and colored options including red, blue, and amber. Styles range from classic round knobs to diamond-cut designs and skull or flame patterns. Most drivers choose chrome or black to match their existing dash trim. For a custom look, mix different styles for various controls - many drivers use larger knobs for frequently used controls like fan speed and smaller ones for less-used functions.
Can I return or exchange these knobs if they don't fit or match my expectations?
Yes, we offer a 30-day return policy on all universal dash knobs. If the knobs don't fit your application or you're unsatisfied with the appearance, return them in new condition for a full refund or exchange. We recommend ordering one knob first to test fitment before purchasing a complete set. Keep in mind that some factory stems may be worn or damaged, preventing proper knob installation - this is not a defect in our knobs but may require stem replacement.
