Upgrade Your Shifting Experience and take control of every shift with the new Billetworkz Weighted Shift Knob " Chonk" - where style meets performance.

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.

Please note that due to the oversized factory reverse lockout, only the Short Teardrop and Chonk will achieve an OEM fit. For all other shapes (Sphere, Lightbulb, Tall Teardrop, Piston, Sledge) we recommend a Reverse Lockout Adaptor for more precise fitment. This is because all other shapes need to sit slightly higher to provide adequate reverse lockout clearance, which creates a small gap between the base of the knob and the lockout.

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. 

Made from solid 304 stainless steel, each knob is precision CNC-machined and powder-coated for a standout finish that elevates your interior.

The added mass delivers smoother, more precise shifts with a satisfying, controlled feel—especially during spirited driving. Expect quicker, more confident gear changes and an immediate improvement in overall shift responsiveness, whether you're commuting or carving through corners.
