Description
Mismatched threads shouldn't force you to abandon a favorite shift knob or settle for one you don't want. This thread reducing insert solves the common fitment problem between 16mm metric shift knobs and the 3/8"-16 SAE threads found on many Hurst shift levers. Whether you're keeping a beloved original knob during a drivetrain upgrade or installing a new 16mm metric knob on your existing Hurst shifter, this adapter delivers a precision fit without modification to either component.
The insert threads into your 16mm shift knob while presenting a 3/8"-16 male thread to mate with the shift lever. The included jam nut locks everything in place, preventing loosening or rotation during aggressive shifting. This simple, effective design weighs just 2 ounces—adding virtually no mass to your shifter assembly.
Fits many popular Hurst shift lever applications commonly found in classic muscle cars and performance builds, including '69-'81 Camaro, '53-'62 Corvette, '36-'46 and '67-'72 Chevy Truck, and '87-'95 Jeep Wrangler YJ. Perfect for TREMEC transmission swaps where you want to retain the original interior appearance or match a specific shift knob to your Hurst Competition/Plus or other 3/8"-16 threaded shifter.
