Learn how to install the POCO Insulated Low-Profile Shift Knob on an M10x1.5 shifter. Step-by-step instructions, common mistakes, and fitment tips.
Quick Answer
Install the POCO Insulated Low-Profile Shift Knob by cleaning the threads, hand-threading it onto your M10x1.5 shifter, and snugging it down without over-tightening. The acetal shell and detachable boot collar make this a straightforward upgrade that can also reduce shift throw.
Why the POCO Insulated Knob is Different
The POCO Insulated Low-Profile Shift Knob uses an acetal outer shell over a stainless steel core. That combination keeps the knob from feeling too hot or cold in extreme weather, while the steel core adds weight for a more solid shift feel.
Because it sits very low on the shifter, the POCO typically reduces shift throw by 5% to 10% compared to most other knobs. That means shorter, quicker shifts once you get used to the new position.
Before You Start: Thread Pitch and Compatibility
This knob is threaded for M10x1.5, which is common on many Honda and Acura shifters. If your shifter uses a different pitch, the knob won't thread on correctly and forcing it can damage the threads.
Check your vehicle's thread pitch before starting. If you're unsure, refer to your service manual or use a thread pitch gauge. The POCO is not designed for other thread sizes, so don't attempt to adapt it.
Step-by-Step Installation
- Prepare the shifter: Remove any existing shift knob. Clean the shifter threads with a rag and a mild solvent to remove grease or debris. Check that the threads are undamaged. A dirty or damaged thread can cause the knob to cross-thread and ruin the shifter.
- Hand-thread the knob: Align the knob with the shifter and turn it clockwise by hand until it seats. Do not use a wrench or tool to force it. The knob should thread smoothly without resistance. If you feel resistance, stop and re-check the thread pitch. Never force it.
- Attach the boot collar: Slide the detachable aluminum boot collar over the shift boot and connect it to the base of the knob. Ensure the boot is not twisted and the collar snaps or screws on securely. A twisted boot can cause the collar to sit unevenly and look misaligned.
- Snug the knob: After hand-threading, tighten the knob an additional quarter to half turn using a firm grip. Do not over-tighten. The knob should be secure but not so tight that it's difficult to remove later. Over-tightening can strip the threads or crack the acetal shell.
- Test the shift pattern: Start the engine and shift through all gears. Confirm the knob doesn't loosen and that the throw feels consistent. If the knob rotates during shifting, tighten it slightly more. If the knob loosens after a few drives, re-snug it and consider a thread-locker designed for shift knobs.
