Description
You've got the perfect shift knob - the one that fits your hand just right - but the threads don't match your new shifter. This thread reducing insert solves that problem by adapting any shift knob with 16mm internal threads to fit shift levers with 8mm x 1.25 external threads.
The machined insert threads directly into your 16mm shift knob's internal bore and provides clean 8mm x 1.25 male threads that screw onto your shift lever. The included jam nut locks everything in place, preventing the adapter from loosening during aggressive shifting. The result is a solid, play-free connection that feels like a factory-threaded setup.
Whether you're swapping transmissions and want to keep your favorite knob, upgrading to an aftermarket shifter with different threads, or installing a new knob that doesn't match your existing lever, this adapter bridges the gap. The 8mm x 1.25 thread pitch is common on many import vehicles and aftermarket shifters, making this a versatile solution for cross-platform builds.
