WHAT'S MY SHIFT KNOB THREAD SIZE?

75% of all our shift knobs come standard with a 16mm x 1.5 master insert that will receive our threaded reducers to accomodate all vehicle shifter sizes. Any size master is available upon request, whether it be threaded or non-threaded (no threads).

If you are not sure what size your shifter is, and you believe it is the stock shifter, then use this as a guide, once you have figured it out, then to be sure you can visit your local hardware store and ask for a JAM NUT in that size to test it. If it fits, viola! you know the size to choose. If you still are unsure after looking at this, please call us - We'd be happy to try and solve your mystery.....512-773-2674
