Construction & Design

The Billetworkz Automatic Shifter is expertly crafted from high-grade 6061 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. Each shift knob undergoes a meticulous CNC machining process to achieve precise dimensions and a flawless fit. After machining, the knob is polished to a mirror-like finish before receiving a hand-applied anodized coating that creates the stunning Purple Cosmic Space effect. This anodizing process not only delivers vibrant, multi-color aesthetics but also provides a tough, scratch-resistant surface that stands up to daily use.

The lockout mechanism is engineered for durability and smooth operation, replacing the factory shift button with a push-down collar that offers a more tactile and responsive shifting experience. The entire assembly is designed to fit perfectly on your Toyota GR Corolla’s automatic shifter shaft, ensuring a clean, factory-like installation without compromising performance or safety.
