Product Details:

Meet Ashiko, weighing in at 735 grams! The broader cylindrical surfaces make side-arm shifting effortless while providing a domed top face for palm shifting.

Whether side-arm or palm shifting from the top, Ashiko's shape is purposefully designed to make both shifting styles more enjoyable. The side surface is designed to fit the natural curvature of your hand and fingers as they wrap around the shift knob as you dictate direction and movement. The domed top surface is intended to compliment palm shifting, giving you an ideal surface area for confident shifting.

WEIGHT: 1.62 lbs. | 735 grams

HEIGHT: 2 11/32" | 59.2 mm

DIAMETER: 2 3/32" | 52.8 mm


With the weight in all the right places, Ashiko redefines your shifting experience through the look and feel of how you shift into gear. You will experience smoother and faster shifts!


Well, to put it as simply as we can, the heavier the knob, the easier it will make shifting feel. Its not magic, its physics. Weight in motion directly relates to how an object will react to an opposing force. In this case, the opposing force is the gate pattern and counter springs that are connected to your shift arm that tell you the shift pattern of your car. The difference felt when shifting into the next gear requires far less effort due to the additional momentum created by the increased mass.


CNC TURNED - The Ashiko is cnc machined from 303 stainless steel. Machining stainless steel is not an easy task. It requires close supervision of Raceseng's cnc turning centers and tooling to ensure a flawless part and surface finish.

ENGRAVED - The Ashiko is then engraved with Raceseng's signature shift gate pattern on our vertical milling machine. You have the choice, get the shift gate pattern engraved for the slick graphic design or not engraved for a smooth and clean design.

HANDWORK - The final touch is done completely by hand. Raceseng brush finishes each shift knob, one at a time by hand on a high speed electric motor.
