We put one on my wife's Thing. She was too short to get 3rd gear in the stock shifter.
It installed pretty easily and works fantastic. My wife vigorously shifted it, even though I explained it is a short shifter and doesn't need a lot of effort to change gears. She knocked it out of alignment and I had to readjust after a month or so. When it isn't, the reverse gate doesn't work well (or at all).
After a few months, it needs adjustment again. It's a small thing but we like the shifter a lot
