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 or the newer style wide-bottomed knobs. 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 available in Matte Black Aluminum (1924-K1) or Turned Stainless Steel (1924-K2) finishes.

Kit Contents:
  • 1x Shift Boot Collar
  • 1x Flat-Bottomed Knob Binding Nut (part # 1924-03)
  • 1x Boss-Bottomed Knob Binding Nut (part # 1924-01)
  • 4x Small Cable Ties


NOTE ABOUT SHIFT BOOTS AND CABLE TIES: On some shift boots, the supplies zip ties may not reach around the whole boot. Avoid using a larger cable tie as it will not fit into the groove on the boot collar as well. Instead, use 2 of the supplied cable ties attached together to reach around the whole shift boot. The supplied cable ties are quite narrow and are selected to fit into the boot collar. If you need more cable ties, similar cable ties can be purchased (normally in black though) from most hardware stores near you.
