Billetworkz Automatic Shifter - "Chonk" - Fits Subaru CVT: WRX (15–21), Crosstrek (13–23), Forester (14–18), Impreza (12–23), Legacy/Outback (10–14)

Upgrade Your Shifting Experience with the Billetworkz Shift Knob and Lockout System, a direct replacement for your factory automatic shift knob. This setup not only enhances the look of your interior, it provides a crisp, mechanical engagement for a more performance-oriented feel. 

The Chonk is our biggest and heaviest shift knob yet, built with an oversized feel and serious weight to help deliver smoother, faster, and more confident shifts.

Designed for drivers who prefer a heavier-than-average knob, the Chonk fits naturally in your hand and helps create the buttery-smooth shifting feel enthusiasts love.

Engineered with an internal counterbore design, the Chonk is made to work with a wide range of reverse lockouts—including larger factory styles found on newer Ford Mustang, Ford Bronco, Chevrolet Cruze, Jeep Wrangler, Toyota GR Corolla, and Ford Focus ST/RS. 

Our exclusive design replaces the factory push-button with a custom pull-up lockout, delivering a clean, mechanical engagement and a more performance-inspired driving experience.

Complete the look with a solid 304 stainless steel shift knob, precision CNC-machined and finished with a durable powder coat for a premium, long-lasting finish. The CNC-machined aluminum lockout mechanism is available in multiple colors for a fully customized appearance.

This system gives your interior a clean, performance-driven look with everyday usability.
