Detroit Speed Billet Aluminum Dash Knobs are a subtle and easy way to upgrade the interior of your classic car. They are similar in appearance to the stock plastic knobs they replace on each dash to retain a stock-type look. Knobs attach to the factory switch stalk with a set screw and secure firmly in place. Each knob and bezel is CNC machined from solid billet aluminum for good looks and lasting durability. All knobs are sold individually unless specified otherwise.
