Construction & Design

Each Billetworkz shift knob is meticulously crafted from premium 6061 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. The manufacturing process begins with precision CNC machining to achieve exact dimensions and smooth contours. After machining, the knobs are polished to a mirror finish, creating a flawless surface that enhances the anodizing process.

The anodizing is performed by hand using a specialized technique that builds a robust, protective layer on the aluminum. This not only provides vibrant, lasting colors but also significantly improves scratch resistance and wear durability. The combination of high-quality materials and expert finishing ensures that your shift knob will maintain its appearance and performance over time.

Installation & Fitment

Installation is straightforward for owners of 2022 and newer Subaru BRZ and Toyota GR86 models equipped with a 6-speed manual transmission. The Short Teardrop shape is designed to fit OEM reverse lockout mechanisms without modification. For all other shapes—Sphere, Lightbulb, Tall Teardrop, Piston, and Sledge—a Reverse Lockout Adaptor is recommended to achieve proper clearance and eliminate any gap between the knob base and the lockout mechanism.

The shift knob threads directly onto the factory shift lever, making installation a simple, tool-free process for most users. This upgrade provides a secure, comfortable grip and enhances the tactile feel of your shifting experience.
