Review on MAIKER Black Auto Gear Shift Lever Knob Shifter Transfer Case Handle Kit Compatible with Jeep Wrangler JK 2011-2018 by Adam Johnson

Aluminum 6065. Designed for M8 shaft. Used socket head screws for tightening around the shaft. When tightening, the hole popped out. I used longer hex head screws as the holes already ground couldn't fit exactly. If you know this is for an M8 shaft you don't know why they didn't make a set screw or thread. Or just make it tighter and use o-rings inside. The handle shifts and moves because it doesn't tighten.
