For the extra bit of style and performance, add a Kartboy Shift Knob to your
Kartboy Shift Lever (works with the stock lever as well.) This computer designed
and CNC turned Aluminum knob fits the hand with comfort, but allows a firm grip
for crucial shifts. No set screws or cheezy adapter sleeves to add, it is
internally threaded. For the ultimate in compatibility, a groove is included to
hold up the shift boot. To top it all off, a tasteful Kartboy Shift Pattern logo
is added.
