Meet Jack. All treats, no tricks.

Bring spooky season along for the ride with the Billetworkz “Jack” Weighted Shift Knob. With a bold, glossy orange finish and a mischievous jack-o’-lantern grin, this limited edition Halloween knob brings personality to your interior and a satisfying weighted feel to every shift. You can also add a Shift Pattern to the top of the knob if you want!

Even Jack needs a Halloween outfit. Every Jack purchase includes a FREE “Trick or Treat” shift knob hoodie, featuring a black design with white lettering and matching white drawstrings. It’s the finishing touch for your spooky setup.

The added mass delivers smoother, more precise shifts with a satisfying, controlled feel—especially during spirited driving. Expect quicker, more confident gear changes and an immediate improvement in overall shift responsiveness, whether you're commuting or carving through corners.
