The Thread-On Skulls Pistol Grip Gearshift Knob is a practical and stylish addition to your vehicle. With its chrome finish and 3-dimensional skull design, it adds a unique touch to your gearshift. Made from die-cast aluminum, it is durable and built to last. The 9/10 speed chrome adapter base and machined 1/2 inch-13 thread ensure a secure fit. Each knob comes with a removable thread lock to prevent loosening. It fits most 9/10 shifters, but please note that it is not compatible with models equipped with D-shape shift knobs.
