Upgrade Your Shifting Experience and take control of every shift with the Billetworkz Manual Shift Knob, designed specifically for 6-Speed Mazda manual transmissions with Reverse in the Left Up position. This version features a silver laser-engraved 6-Speed Shift Pattern with our "Japanese + Evil M" engraving, adding a unique look to your interior that is made to last.

Each knob is CNC‑machined from 6061 aluminum and polished to a mirror finish before undergoing a hand‑crafted anodizing process. Every color combination is individually applied using an intensive technique, making each knob truly one‑of‑a‑kind. The anodized layer not only provides a stunning, vibrant finish but also delivers exceptional durability and scratch resistance— built to stand up to daily driving while maintaining its striking look.

All Mazda Shift Knobs are designed to replace your OEM shift knob for a clean, factory-style fit and feel. Thread pattern: 10x1.25mm.

Want the cleanest install? Add a Billetworkz Boot Retainer to remove the gap between your shift boot and knob.

Shift knob and retainer

The shift knob is awesome but the retainer doesn’t retain anything and my boot just flops around and it chipped like nothing when I went to tighten it so now it’s jagged because it’s a soft material. Retainer is not worth the price because now I just have to replace it and it’s not functional

Awesome Shift Knob!

I bought this as a birthday present for my husband to install in his MazdaSpeed3, and he absolutely loves it! The colors, the shape, and the weight were all perfect. Very easy to install, looks great in his car. Thank you for an awesome product and for making a happy customer of us both.

Cool

The knob is the tits. Definitely very well made. They give u a bolt that threads onto the shaft that the knob threads onto and a keeper nut with it. Those feel like garbage. Getting the knob to line up correctly is pretty hard to do. I ended up tossing the keeper nut and just tightened it on as tight as I could and it lined up perfectly. Took about 2 months to get. When I contacted them they were very fast to respond and definitely made me feel like they were trying their best to get it done for me. All this during a pandemic so I didint worry too much about the wait time. Would give 5 stars but considering it's custom made I don't see why they couldn't have just tapped the knob to screw onto the shaft without the other pot metal feeling nutts. Over all still very satisfied and would recommend. Thank you again
