Construction & Design

This shift knob is meticulously crafted from high-grade 6061 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. Each knob undergoes a multi-step finishing process beginning with a mirror polish that creates a smooth, reflective surface. The anodizing process is performed by hand using an intensive technique that builds a robust, scratch-resistant layer of color. This not only enhances durability but also ensures the vibrant Green Cosmic Space finish remains vivid over time.

The ergonomic shapes available are designed to provide comfortable grip and precise shifting control, catering to both daily drivers and spirited enthusiasts. The engineering accounts for the unique reverse lockout mechanism found in these models, ensuring optimal fitment and functionality.

Installation & Fitment

Installation is straightforward for most shapes, especially the Short Teardrop, which fits directly onto the factory shifter without modification. For other shapes such as Sphere, Lightbulb, Tall Teardrop, Piston, and Sledge, a Reverse Lockout Adaptor is recommended to achieve proper clearance and eliminate any gap between the knob base and the reverse lockout mechanism. This adaptor ensures a secure, OEM-like fit and prevents interference when engaging reverse gear.

The shift knob threads directly onto the factory shifter shaft, making installation a simple, no-drill process that can be completed with basic hand tools. This upgrade is ideal for owners seeking a high-quality replacement or a personalized touch to their vehicle’s interior.
