The factory Polaris Slingshot shift knob looks like it came off of a tractor. Our Threaded Shift Knob Adapters allow you to run any aftermarket shift knob that has a thread and pitch of either M10 x 1.25 or M10 x 1.5 depending on the brand you select. These thread and pitch options open your aftermarket shift knob options to literally endless possibilities. All of our threaded shift knob adapters are a direct bolt on to your factory Slingshot shift assembly for a seamless installation that looks and feels a heck of a lot better than the OE configuration.
