The Circuit Cylinder 150 fuses function, form and style together to create an unparalleled, performance enhancing and confidence inspiring shift knob.
The ergonomically designed and textured cylinder grip was designed for side arm shifting and features a flattened top which provides a comfortable resting position for your thumb to maintain directional control.
The stainless steel handle is appropriately weighted to remain delicate on your shifter linkage assembly and to prevent the numb feeling commonly found when the weight is set too high in the grip.
The 150mm height reduces your hand’s travel distance and time between shifts while increasing your mechanical leverage and reducing the effort required for each shift throw. The Circuit Cylinder was designed to reduce fatigue during repetitive lateral arm and shoulder movement between the steering wheel and shift knob.
CIRCUIT CYLINDER 150 \
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.

FORM + STYLE
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 designed our Circuit Series to be modular and have the flexibility of interchanging all available components. Individual Circuit Series parts can be purchased in our Component Shop to custom tailor the shift knob to you your needs and preferences.
NO SAGGY SHIFT BOOT
We hate sagging shift boots. Our adapters have a built in shift boot retainer section. Simply use the supplied zip tie to attach your shift boot to the adapter. When the shift knob is installed, it will sit flush with the top of the shift boot.

The birth of Raceseng dates back to 2005 when a father and son were inspired to merge their combined design, engineering and manufacturing skills with their passion for racing. With a legacy of racing history dating back to 1957, the driving goal was to create a company that embodied their passion and knowledge to completely design, develop and manufacture a line of high performance automotive products. Ever since then, we have set out on a journey being well aware that its going to take many years of hard work to build out our vision!
