Bevinsee Shift Boot Collar Adapter M10x1.5 - Black Anodized CNC Aluminum, Reversible with 2 Nuts

Bevinsee's shift boot collar is a black anodized, CNC-machined aluminum adapter that fits M10x1.5 shifter studs and lets you mount a variety of aftermarket knobs quickly and securely.

Designed as a lightweight yet robust interface between your vehicle's factory shifter stud and aftermarket knob, this collar provides precise thread alignment and a corrosion-resistant finish. Machined from aluminum alloy and anodized for durability, the collar is reversible to accommodate different knob base shapes and includes two binding nuts—one for flat-bottomed knobs and another for boss-bottomed styles—so you can install most M10x1.5 knobs in minutes.

How does this collar improve knob installation?

The collar acts as a stable adapter that centers and secures the knob on the M10x1.5 stud. CNC machining ensures tight tolerances for a straight fit, reducing wobble and making thread engagement predictable.

• Precision CNC cuts for consistent thread alignment
• Two included nuts cover flat and bossed knob bases
• Reversible collar profile to match knob base diameters
• Fast, tool-assisted installation in minutes

Will this fit my car's shifter?

This collar is made for shifters with an M10x1.5 threaded stud, a common size on many vehicles. Always verify your vehicle's stud pitch and diameter before purchase; the reversible collar helps adapt to differing knob base geometries.

• Spec: M10 x 1.5 thread pitch
• Works with most aftermarket knobs designed for M10x1.5
• Reversible design to suit varied base shapes
• Includes two binding nuts for wider compatibility

What materials and finish are used, and why they matter?

The collar is crafted from lightweight aluminum alloy and undergoes anodization to improve surface hardness and resist corrosion. The metal construction keeps the collar nearly weightless while remaining strong enough to hold the knob securely under normal driving conditions.

• Aluminum alloy for low weight and strength
• Precision CNC machining for accurate dimensions
• Anodized surface resists oxidation and wear
• Smooth finish for easier knob movement and clean styling

How do I install the Bevinsee boot collar correctly?

Installation is straightforward: choose the nut that matches your knob’s base, flip the collar to the appropriate orientation, thread onto the M10x1.5 stud, and tighten to secure the knob. Basic hand tools or a small socket are all that’s required; follow your knob manufacturer’s torque guidance to avoid over-tightening.

• Select flat or boss nut included in kit
• Flip collar to match knob base diameter
• Hand-start threads, then snug with a wrench
• Confirm secure fit before driving

Who is this for? Drivers who want a reliable, low-profile adapter to fit aftermarket shift knobs onto M10x1.5 studs will benefit from this Bevinsee collar. It’s ideal for enthusiasts swapping knobs for improved feel or aesthetics, DIY installers who value clear compatibility and included hardware, and anyone seeking a corrosion-resistant, precision-machined upgrade that installs quickly without major modification.
