Upgrade your Mustang’s interior with a slim-profile reverse lockout that works with all Billetworkz shift knob shapes and replaces the bulky OEM design.

The Billetworkz Reverse Lockout for 2015+ Ford Mustangs is engineered to enhance both the form and function of your interior. The factory lockout is oversized, restrictive, and often prevents many aftermarket shift knobs from fitting correctly. Our version features a sleeker top diameter, ensuring compatibility with every Billetworkz shift knob shape for a clean, customized look.

Machined from high-quality 6061 aluminum, this lockout offers superior durability without adding unnecessary weight. The anodized finish provides long-lasting color, scratch resistance, and an upgraded aesthetic that transforms your interior instantly.

Compatible with the factory shifter as well as popular aftermarket options—including Steeda and Barton short-throw shifters—this lockout is the perfect foundation for your favorite knob setup. If you want a smoother shift feel, cleaner appearance, and more customization freedom, this is the ultimate Mustang interior upgrade.

Note: Lubricate O-rings before installation for proper function.

Fitment: Ford Mustang — 2015+ (manual transmission) - Works with factory shifters, Steeda short-throw, and Barton short-throw assemblies.
