M12x1.5 Delrin Shift Knob

This is a direct fit/replacement for any M12x1.5 threaded shift knob and will not rattle like many universal knobs do. The hole extends as deep as possible to give you the lowest possible installed height. 

The round knobs are the most popular style due to their comfort. Delrin is an ideal material for this due to it's superior strength/weight ratio and low thermal conductivity.
