We go to great lengths to bring you the very finest shift knobs available. Each is hand carved and faithful in design, and since each tree has it's own personality in grain, pattern, density, color, hue and feel, we personally inspect each one and guarantee the quality and finish to be perfect. This assures you a knob that is not only beautiful to look at but sensuous to the touch as well. If you are uncomfortable with your mechanical skills, please have knobs professionally installed. Overall size of shift knob and shaft is 7 inches.
