Category: Automatic Adaptor

Upgrade your Subaru’s interior and shifting precision with the Billetworkz CVT Shift Knob Adapter—engineered to integrate seamlessly with most factory automatic CVT shifter assemblies.

This precision CNC-machined aluminum adapter replaces the factory shift knob button with our custom spring-loaded pull-up lockout system. Unlike other designs that require lifting or pressing on the entire knob—our fixed-position setup keeps your knob secure, eliminates rattles, and delivers a clean, confident shifting feel. Multiple anodized finishes available.

To engage reverse or drive, simply lift the lockout collar. The spring-loaded mechanism automatically resets into position, preventing accidental shifts and maintaining a sleek, factory-plus appearance.

Threaded for 12x1.25mm shift knobs (Billetworkz knobs guaranteed to fit; third-party knobs may vary based on bore size)

Customer Reviews (4.6 / 5 · 5 reviews)

Avery ★★★★★

Installation took maybe ten minutes and now my WRX’s shifter feels precise instead of vague. The aluminum build mates perfectly with the stock assembly, no wobble at all.

Kevin A. ★★★★★

The adapter feels much more solid than the plastic piece it replaced, and now I can reach the paddle shifters without stretching. My Impreza's shifts are noticeably crisper, and the install was straightforward with the included instructions.

Michael ★★★★★

Snapped right onto my Crosstrek's factory CVT shifter without any wobble, and the threading lined up perfectly on the first try. Feels way more solid than the plastic knob that came stock, and it hasn't loosened up after a couple months of daily driving.
