Construction & Design

The Billetworkz Automatic Shifter is crafted from high-grade 6061 aluminum, 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 in the striking Blue Cosmic Space color. This anodizing technique not only creates a visually stunning effect but also provides a durable, scratch-resistant surface that withstands daily use.

This robust design contributes to a refined, rattle-free feel that complements the sporty character of the GR Corolla interior.
