Description:
The finishing touch that looks good with any shift knob
Gone are the days of sagging shift boots, broken plastic shift boot collars, and shift boot collars that don't match the diameter or style of your shift knob. ACUITY designed this Shift Boot Collar Upgrade to allow use of virtually any M10x1.5 shift knob in your Honda without sacrificing fit and finish between the shift boot and shift knob. This kit includes 2 binding nuts, one meant for flat-bottomed knobs, and the other meant for boss-bottomed knobs (like modern Civic Type R and Honda Factory Performance designs). The boot collar is reversible and can be flipped to match your knob's base diameter, whether it be a traditional narrow-bottomed knob (with a 22mm lower diameter) or the newer style wide-bottomed knobs (with a 28mm lower diameter). An integral retaining feature lets you easily pop the boot collar on and off many times without problems, so you no longer have to worry about breaking the OEM plastic boot ring when removing your shift knob. The supplied binding nuts are turned and milled from stainless steel and have flats for a 12mm open-ended wrench. The boot collar is made from 300 series stainless steel and is all markings are laser etched.
