Upgrade your interior with the Billetworkz Automatic Shift Knob Adapter, designed specifically for 2015–2025 Ford Mustang models (GT, EcoBoost, and V6 trims). Note: Not compatible with GT350 or GT500 models.
This adapter allows you to install any Billetworkz shift knob on your automatic Mustang, thanks to our precision-engineered lockout system that replaces the factory knob’s integrated button.
Unlike other solutions that require you to push down on the shift knob—causing unwanted movement and safety concerns—our lockout mechanism keeps the shift knob fixed in place. Simply press down on the spring-loaded lockout collar to engage reverse or drive. The collar then returns to position automatically to prevent accidental shifts and eliminate interior rattle.
Access our step-by-step installation guides and install your Billetworkz products with confidence. Each guide provides clear instructions to ensure perfect fitment every time.
Most orders ship within 1–3 business days, but processing times can vary depending on inventory, color selection, and customization options.

It feels really nice and operates smoothly so far. Highly impressed with the quality!
The shifter was an easy install and looks and works just like it's supposed to.
It went in my woman's 21 premium GT, and she couldn't be happier!
She even told me today that the push down lock out mechanism is more user friendly and intuitive than the factory original.
Great product!
Got a machined aluminum knob for my Dark Horse and a weighted black ball for my GT. They look a feel great! Also added the manual shift trim to clean up the look.
Love it!
