While heavy shift knobs feel great for DD use, they can easily damage synchros if not careful in race conditions. Alternatively, too light a knob will make every notch within the gear box feel magnified. The Karcepts Weighted Black Delrin Shift Knob incorporates the perfect amount of ballast by utilizing a stainless steel insert, encased in a Delrin outer shell. The Delrin material offers excellent thermal properties, where in extreme temperature conditions, it will neither be too hot or cold to the touch. Along with the weight and material composition, this knob encompasses the desirable feel of a smooth ball type shifter, but with the added elegance of a teardrop profile.
