Construction & Design

The Billetworkz Automatic Shifter is meticulously crafted from high-grade 6061 aluminum, a material prized for its excellent strength-to-weight ratio and corrosion resistance. Each component is CNC-machined to exacting tolerances, ensuring a perfect fit and smooth mechanical function. The shift knob undergoes a multi-step finishing process, beginning with a mirror polish that highlights the metal’s natural luster, followed by a hand-applied anodizing treatment that creates the distinctive Black Fire Splash pattern. This anodizing not only enhances visual appeal but also provides a durable, scratch-resistant surface that withstands daily use.

The innovative lockout collar mechanism replaces the conventional push-button with a push-down design that remains fixed during shifts. This design choice improves driver feedback and safety by preventing accidental gear changes while maintaining a refined, rattle-free feel. The mechanism’s instant reset after each shift ensures consistent performance and a confident driving experience.
