Bevinsee M10x1.5 Shift Boot Collar — CNC Aluminum Black, Reversible Fit & Anodized Finish

Bevinsee's M10x1.5 shift boot collar is a CNC-machined aluminum adapter that provides a precise, corrosion-resistant mounting solution for most M10x1.5 shifter knobs.

This machined boot collar replaces flimsy factory collars with a lightweight, hard-anodized aluminum ring that secures both flat- and boss-bottom shift knobs. Built to tight tolerances and finished to resist oxidation, the collar is reversible to match a variety of knob base diameters and comes with two binding nuts to simplify installation. It’s designed for drivers who want a durable, neat-looking connection between knob and boot without altering their vehicle’s factory threads.

How does the Bevinsee collar improve my shifter's fit and finish?

The collar eliminates sloppy gaps and uneven compression that often occur with stock plastic collars. Because it is CNC-machined from aluminum and anodized, it creates a uniform mating surface that keeps the boot snug and the knob centered under heavy use.

• High-precision CNC machining for a consistent diameter and concentric fit
• Anodized finish prevents visible wear and discoloration
• Reversible collar profile adapts to different knob base sizes
• Two included binding nuts cover flat-bottom and boss-bottom knobs

Will this collar work with my M10x1.5 shifter knob?

The Bevinsee collar is compatible with the vast majority of aftermarket and OEM knobs that use the M10x1.5 thread standard. It’s intended to thread directly onto the car’s shifter shaft and accept the knob’s mounting hardware without needing thread adapters.

• Designed specifically for M10x1.5 threaded shifters
• Includes two different binding nuts for common knob bottom shapes
• Reversible collar face accommodates varying knob diameters
• Installable using basic hand tools in minutes

How durable is the aluminum and finish under daily driving conditions?

Constructed from aluminum alloy, the collar combines low weight with high strength to withstand repeated shifts and temperature cycles. The anodized surface improves scratch and corrosion resistance compared with untreated metal, helping keep the trim looking new over time.

• Lightweight aluminum alloy resists deformation under load
• CNC machining provides tight tolerances for long-lasting fit
• Hard anodized coating reduces oxidation and surface wear
• Maintenance-free under normal interior conditions

How easy is installation and what comes in the box?

Installation is straightforward: thread the collar onto the shifter, position the boot, and tighten the supplied binding nut appropriate for your knob type. No special tools or modifications are required for most vehicles that use M10x1.5 threads.

• Includes one reversible aluminum collar and two binding nuts
• One nut fits flat-bottom knobs, the other fits boss-bottom knobs
• Quick install with common hand tools—no cutting or drilling
• Fully tooled for a secure, clean finish in minutes

Who is this for?

The Bevinsee M10x1.5 shift boot collar is ideal for drivers upgrading to an aftermarket knob, restoring interior trim, or replacing a worn factory collar. It suits hobbyists who value precision fit, tuners who want a clean, durable look, and anyone seeking a simple, reliable way to secure M10x1.5 shift knobs without altering threads or resorting to adhesives.
