Construction & Design

The Billetworkz Automatic Shifter is crafted from high-grade 6061 aluminum, CNC-machined to exacting tolerances for a perfect fit and finish. The shift knob undergoes a meticulous polishing process to achieve a mirror-like surface before being hand-anodized with a unique toxic splash pattern. This anodizing technique not only creates a striking multi-color appearance but also provides a robust, scratch-resistant coating that withstands daily use.

The lockout mechanism is engineered to replace the factory button with a push-down collar that offers a more tactile and reliable engagement. This design keeps the knob fixed in place, reducing unwanted movement and enhancing driver confidence. Every component is built to deliver a refined, rattle-free feel that elevates the interior ambiance while supporting spirited driving.
