Description
Thread mismatches between shift knobs and performance shifters have frustrated builders for years. This precision thread reducing insert solves the compatibility problem, letting you retain your favorite shift knob when upgrading to a new shifter or mate a new knob to the threads you already have. The adapter bridges the gap between the common 16mm knob threading and the 12mm x 1.75 metric threads found on many performance shifters and OEM applications.
The insert provides a clean, permanent solution that maintains proper shift knob height and feel. Unlike bulky universal adapters that introduce play, this reducing insert threads directly into 16mm-threaded knobs and accepts 12mm x 1.75 shift lever threads with a precision fit. The included jam nut locks the knob in position under aggressive shifting and prevents loosening during spirited driving.
This adapter fits popular performance shifter applications including '83-'04 Mustang levers, Ford GT, Shelby KR/Super Snake, Shelby American Generation 1 shifters, Steeda Tri-ax units, and MDG Camaro Retro shaft handles. At just 2 ounces, the adapter adds negligible mass while delivering the threading solution you need for a proper fit.
