Construction & Design

The Billetworkz Automatic Shifter is crafted from premium 6061 aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. Each component is CNC-machined with precision to ensure perfect fitment and smooth operation. The shift knob undergoes a meticulous polishing process to achieve a mirror-like finish before being hand-anodized. This anodizing process not only creates a visually striking multi-color Nebula Black Splash effect but also provides a durable, scratch-resistant coating that withstands daily use.

The innovative lockout mechanism replaces the factory shift button with a push-down collar that remains fixed in place, enhancing safety and control. This design reduces the chance of accidental gear changes while delivering a solid, mechanical feel that complements the sporty character of the GR Corolla.

Installation of the Billetworkz Automatic Shifter is straightforward and designed to be a direct swap with the factory automatic shift knob on Toyota GR Corolla Hatch and Sedan models from 2019 and newer. No modifications or special tools are required, making it an ideal upgrade for enthusiasts who want a quick and clean interior enhancement.
