Construction & Design

The Billetworkz Automatic Shifter is crafted from premium 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 knob is polished to a mirror finish before undergoing an intensive anodizing process that creates a durable, scratch-resistant surface with vibrant color accents. This meticulous hand-anodizing technique allows for unique multi-color designs, such as the striking black base with red splash featured on this model.
