The factory reverse lockout collar on the Focus ST, Focus RS, and Fiesta ST suffers from an oversized top diameter that blocks compatibility with most aftermarket shift knobs. Billetworkz solves that with a slim-profile billet replacement that clears the way for any shift knob in their lineup, giving owners a clean, cohesive interior upgrade without compromise. CNC-machined from solid 6061 aluminum and finished with a custom anodize coat, this collar pairs function with aesthetics in a package that installs as a direct OEM replacement.
Slim profile, maximum compatibility. The reduced top diameter is the core change here. It lets every Billetworkz shift knob shape seat and function correctly, eliminating the fitment headache that comes with the stock collar's bulky geometry. No trimming, no adapters, no workarounds.
Precision machining and a durable anodized finish. CNC machining holds tight tolerances so the collar fits the factory shifter housing exactly as the OEM piece did. The anodized coating resists scratching and daily wear, and it comes in six color options: Red, Black, Blue, Cosmic Purple, Cosmic Blue, and Cosmic Red. Match it to your shift knob or mix for contrast.
Drop-in installation. The lockout replaces the factory collar with no modifications to the shifter assembly. No drilling or cutting is required. Swap it in, pair it with a Billetworkz shift knob, and the interior upgrade is complete.
