Bevinsee M10x1.5 Shift Boot Collar — Black Anodized CNC Aluminium, Reversible Fit with Two Binding Nuts

Bevinsee's M10x1.5 shift boot collar is a lightweight, CNC-machined aluminum adapter that secures most M10x1.5 shifter knobs and lets you swap knobs quickly while preventing wear at the boot opening.

This boot collar upgrade is crafted from anodized aluminum and made to fit a wide range of aftermarket shift knobs that use the M10x1.5 thread. It includes two interchangeable binding nuts so you can mount flat-bottom or boss-bottom style knobs without modifying the knob base. The reversible collar profile and precision CNC machining make installation straightforward and give a clean, finished look where the shift boot meets the knob.

How does this collar improve my shifter knob installation?

The precision-machined collar provides a stable seat for the knob and hides uneven boot edges, reducing play and rubbing. Its reversible design accommodates different knob base diameters, so you often won't need extra spacers.

• Reversible collar face to match various knob bases
• Includes two binding nuts for flat and boss-bottom knobs
• Anodized finish resists corrosion and wear

Will it fit my car and aftermarket knob?

The collar is compatible with most aftermarket and OEM shifter knobs that use the common M10x1.5 thread. Check your knob’s thread measurement and profile—this collar is designed to work with knobs that accept a binding nut installation.

• Two nuts included for different knob bottoms
• Reversible collar to match base diameters

How difficult is the installation and what tools are needed?

Installation is quick and generally requires only basic hand tools. The collar and included nuts are machined to precise tolerances so parts thread together smoothly and tighten securely in minutes.

• Use a wrench or socket to tighten the nut evenly—no drilling or cutting
• Reversible orientation makes alignment easier during install
• Fully installed in minutes with standard tools

What materials and finishes protect the collar from everyday use?

This collar is made from aluminum alloy and finished with anodization to resist corrosion and surface wear. The CNC machining produces a clean edge and consistent thread engagement for long-term reliability.
