Free Insert Installation with Purchase of Bawdy Partz Custom Shift Knob.  The threaded insert option will be shown as a product option on products that accept the insert.

Sizing your Threaded Insert

With most vehicles, the inserts are installed straight up from the bottom. Harley and Indian stock hand shifters are threaded 3/8×24 and need to be installed at an angel to sit level on left and right handed shifters. Please keep this in mind when ordering.

There are 15 or so different thread sizes that fit the different cars, trucks, boats and bikes. You can determine your thread size by taking the existing shift knob to your local parts house or hardware store. Match a bolt to the shift knob and the tread size will be marked on the bin or box from witch it came.

We can help you find the size you need.
