Upgrade your Subaru’s interior and shifting precision with the Billetworkz Auto Shift Knob Adapter—engineered to integrate seamlessly with your 2002-2009 Automatic Chevrolet Trailblazer.

This precision CNC-machined aluminum adapter replaces the factory shift knob button with a fixed-position lockout system—providing a cleaner, safer, and more stable shifting experience. Unlike other setups that require pressing down on the shift knob itself, our design keeps the knob locked in place, eliminating unwanted movement and interior rattle. Multiple anodized finishes available.

To shift into reverse or drive, simply press down on the spring-loaded lockout collar. It smoothly returns to its original position after use, preventing accidental gear changes and enhancing driving confidence.

Billetworkz knobs guaranteed to fit; third-party knobs may vary based on bore size.

Customer Reviews (4.8 / 5 · 5 reviews)

Carter ★★★★★

I was pleasantly surprised at how solid the aluminum feels in hand, definitely sturdier than the plastic piece it replaced. Installation took maybe ten minutes and the shift action is noticeably more precise now.

Joseph G. ★★★★★

The adapter's aluminum construction feels solid and precise, making the shift action noticeably cleaner than the stock setup. Took about ten minutes to install in my 2005 Trailblazer.

Charlotte Z. ★★★★★

The adapter threaded right onto my Trailblazer's shifter with no wobble at all, and my aftermarket knob sits perfectly straight now. Shifts feel way more solid than the stock plastic setup ever did.
