With its low-profile, reduced shift throw, clean shift boot integration, and insulated outer shell. In 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. What to Expect ACUiTY's POCO knobs sit low, much lower than most stock and aftermarket knobs. Most knobs sit around 25mm (1 inch) or higher above the top of the actual shift lever. The POCO sits only 3-4mm taller than the top of the shift lever when mounted. The POCO-Insulated builds on its predecessor by combining an insulated acetal outer shell with a stainless steel core to deliver a weighted knob that is gentle on the hand even in very hot or cold weather. How it Works The POCO's boot collar is affixed to the shift boot using a low-profile cable tie (3 are supplied with each kit); the knob threads down on the shift lever until it stops. Once both parts are installed, the shift boot collar clips into the shift knob and installation is complete. Each POCO-Insulated features a heavy, stainless steel inner core and an insulated acetal outer shell in a tasteful, hand-turned finish. The shift boot collar is aluminum and features a satin black anodized finish. An elastomer ring in the knob provides the collar retention feature, similar to our very popular 1924 shift boot collars. All lettering is laser-etched for durability.
