With or without? All depends on your personal preference. Our signature shift gate engraving was designed to be graphically clean while giving your shift knob a unique aesthetic.

The engraving is cnc machined into the shift knob using a small .0625" solid carbide ball end mill.


With the weight in all the right places, Slammer 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 Slammer 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.


We specifically designed the Slammer to fit medium to x-large size hands.

Side Arm

Angled Overhand

Full Overhand


Shifting Positions

The Slammer was designed for multiple shifting positions including side arm, full overhand, angled overhand and overhand shifting positions. To make a shift knob work for all of these positions, the shape of the Slammer is not the traditional ball shaped shift knob. The proper ergonomics behind these shifting positions required a unique shape, one with a diminishing side profile, full form shape at the bottom and a flatter top shape to fill your palm.

Design Driver

We believe in the power of the design process to create incredible products. Every shift knob start it's life as an idea that is translated into countless ideation sketches where form and details evolve. We take those sketches and further develop them in solid modeling software to define the form and ergonomics of the shift knob. The goal of this process is to perfect the balance between form and function to create an unparallelled product and brand experience.
