Product Details


635 grams. That's the number you need to remember. The Slammer is exactly what the name entails. The shape and mass of this shift knob makes for one of the most enjoyable shifting experiences.

Slammer Shift Knob from Raceseng


The shape of the Slammer is not the traditional ball shaped shift knob for a reason. The ergonomics behind an overhand grip shift position require a full form shape at the bottom and a flatter top shape to fill your palm. The combination of these elements drove the shape of the Slammer.

Smoother Shifting!

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.

    • 2 1/16" | 52.4 mm


  • 635 gram Stainless Steel Shift Knob with 6-Speed Pattern Engraved
  • Threaded Adapter Kit & Shift Boot Retainer - For cars with a threaded shifter arm which require our M12 x 1.5mm - Threaded Adapter Kit. The shift boot retainer is part of this kit and will allow you to zip tie your shift boot to the underside of the shift knob.


Finishing Touch:

The finishing touch on the Slammer is our optional shift gate pattern engraving. After the Slammer is powder coated, we put it back into our CNC machine to engrave the shift gate pattern. The stainless steel shows thru the powder coating which makes your shift gate pattern pop! The engraving below is for representation only. We will engrave the correct shift gate pattern in your shift knob.
