Raceseng Ashiko - Texture - M12x1.25mm

A monument to the art of shifting. The Ashiko weighs in at 735 grams and features broader cylindrical surfaces to make side-arm shifting effortless while providing a domed top face for palm shifting. The finishing touch is a powder coat finish with a subtle texture for enhanced grip. Available in your choice of black, graphite or red.

The Ashiko comes with an adapter that will seamlessly mount it on your car's shifter arm with OEM fit and finish.

Part of our Mass Series collection, the Ashiko is weighted for performance shifting. The use of stainless steel creates a shift knob with mass to smooth out notchy shifting.



The texture finish is achieved through a meticulous powder coating process which includes multiple stages of careful hand work. The shift knobs come off our cnc machines with a super smooth surface finish, then they are gently glass beaded to promote powder coating adhesion. A coat of electrostatically charged powder is applied, then baked to cure the powder which creates a subtle textured finish for a confident shifting grip.



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!

How? 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.



We take fitment seriously. The Ashiko comes with a precision cnc machined adapter that will fit your car's threaded shifter arm with OEM fit and finish. The adapter requires simple steps to install and allows you to adjust the shift gate engraving orientation with ease.



The optional shift boot retainer keeps your shift boot securely retained to the bottom of your shift knob. Simply attach your shift boot to the retainer with the supplied zip tie and slide the boot retainer into the bottom of the shift knob.

The shift boot retainer is not required if you have a car with a reverse lockout.
