Construction & Design

The shift knob is precision CNC-machined from 6061 aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. After machining, each knob is polished to a mirror-like finish, enhancing its visual appeal and smooth feel. The anodizing process is carefully hand-applied, creating a vibrant, durable coating that resists scratches and fading even under the rigors of daily driving. This meticulous construction ensures that the knob not only looks exceptional but also withstands the test of time.

The silver laser-engraved shift pattern and "Heartbeat" design add a subtle yet distinctive aesthetic, elevating the interior styling of your Toyota GR Corolla or Corolla Hatch without overpowering the cabin’s factory design language.

Installation & Fitment

Installation is straightforward and designed to fit the Toyota GR Corolla and Corolla Hatch models. The Short Teardrop shape achieves an OEM-style fit without any additional components, thanks to its compatibility with the factory oversized reverse lockout. Other shapes such as Sphere, Lightbulb, Tall Teardrop, Piston, and Sledge require a Reverse Lockout Adapter to ensure proper clearance and fitment. Without this adapter, these shapes will sit slightly higher, creating a small gap between the knob base and the lockout mechanism.

This shift knob is ideal for enthusiasts looking to personalize their vehicle’s interior while maintaining functional integrity and comfort during gear changes.
