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 to exacting tolerances, ensuring a precise fit and smooth operation. The shift knob undergoes a meticulous polishing process to achieve a mirror-like finish before being hand-anodized. This anodizing technique not only provides a visually striking multi-color effect but also creates a durable, scratch-resistant surface that stands up to daily use.

The innovative lockout mechanism replaces the standard shift button with a push-down collar that remains fixed in place, delivering a mechanical feel that enhances driver confidence. This design reduces unwanted play and noise, contributing to a more refined and engaging driving experience.
