NOT a Copolymer Shift Knob. Made from the superior material Delrin. Wonderful feel to this material, never too hot or too cold. The Delrin Shift Knob is strong enough to not require a brass insert to be used, which coincidentally the knob is stronger without an insert, and it holds a thread very well too.

This simple design gives the best bang for the buck. Finish brushed for your viewing pleasure. Hand Polished Delrin knobs are available with a highly reflective surface and offer a "sticky' feel suited for performance or track environments. These knobs do not wear! Fits all Impreza WRX and STi, Legacy, Forester. Does NOT fit Automatic transmission cars.
