n recent years, countersunk knobs have become a popular way to achieve shorter shift throws and reduced knob height without modifying the shifter itself. A core problem with most countersunk knobs is that they don't fit well to the shift boot, leaving the shift boot to sag and the shift lever exposed. ACUiTY's POCO knob is the answer with its low height and built-in shift boot collar, the combination of which permits a very low shift knob height combined with a clean fitting shift boot.
