The OG Plum shift knob is our first two piece shift knob design in a limited quantity anodized Plum color. These Anodized versions are polished to a mirror and then anodized to create vibrant colors. Once these Plum knobs are sold out they will not be restocked. It is the largest diameter measuring 1 7/8” for a solid round feel. Choose insert color, then the thread size to make it exactly how you want it.
