The Circuit Cylinder spawned from the idea of creating a functional, well designed and aesthetically pleasing shift knob intended for competition driving on the track or street. The marketplace is littered with competition shift knobs which lack engineering, testing and refinement to provide the best option to enthusiasts. We knew we could provide what the real competition driver is looking for so we set out to create a competition shift knob that delivers unparalleled performance and features compared to anything else on the market.

Besides the steering wheel, the shift knob is the most driver interactive interior accessory but can have the least amount of integrated design. The Circuit Cylinder flips that script and features a grip that has pure functionality integrated with visually stunning design language. The delrin grip has gently arched sides with a flattened top designed with a specific angle for your thumb to seat. The bead blasted texture enhances the grip, all while remaining cool to the touch. We designed an intentional tangent line around the grip which provides a subtle contour to unite your hand to the grip faster and easier. The final touch is a contrast cut Raceseng icon which visually pops against the satin finish of the delrin grip.




We take fitment seriously and make Threaded (TA) and Non-threaded (NTA) Adapters that will mount the shift knob on your shifter arm with OEM fit and finish. The adapters requires simple steps to install and allow you to adjust the shift gate engraving orientation with ease.

Our shift boot collars were intentionally made to remove boot crack or saggy shift boots.
