Raceseng MT Slammer Shift Knob
2015+ WRX / 2015+ STI
615 grams... That is the number you need to remember. The Slammer is exactly what the name entails. The shape and mass make for one of the most enjoyable shifting experiences. The Slammer works with the factory and aftermarket reverse lockouts and comes with a threaded shifter arm adapter to fit your STI.Details
The Slammer tips the scales at 615 grams and you feel every ounce of that weight while smoothly shifting from gear to gear. The mass of the Slammer helps redefine your shifting experience by allowing the weight of the knob to work in your favor while slamming gears.
WHY?
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.
COMFORT
A shift knob is one of the most touched accessories in the car, short of the steering wheel and pedals. We designed the Slammer to be just as aesthetically pleasing as it is to hold in the palm of your hand.
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.
STAINLESS STEEL
The Slammer is cnc machined from 303 stainless steel. Machining stainless steel is not an easy task. It requires close supervision of our cnc turning centers and tooling to ensure a flawless part and surface finish.
COMPONENTS
THREADED ADAPTER
The Slammer shift knob will come with a billet aluminum threaded adapter with a M12 x 1.25mm thread to fit the shift knob to your STI shifter arm
SET SCREW
A set screw is also included that allows you to easily adjust the orientation of the shift gate pattern and the height of the shift knob. Instructions are included to help you thru the installation process.

Worth it
By shane July 9, 2017Killer look and works great. The set screw makes it easy for the trial and error of installing it correctly so the gates line up perfectly. For me it seems to sit lower than the stock knob and almost makes the shifter seem shorter. This is also a good thing. I wasn't expecting that.

Great Product
By Todd February 26, 2015High quality product and feels great in your hand. Just the right weight to make shifting fun, and looks fantastic in the car. (I much prefer steel to all of those other colored and textured shift knobs) Using it in a Colorado winter, the knob does get a little cold.... it warms up quickly with use, though.
