OME shocks. Not adjustable but also no know to get ripped off.
I also recently discovered that my favorite shock company for road cars, Koni, has a set of shocks for stock height jeeps but not lifted jeeps. Koni shocks are adjustable but I probably no knob. usually you have to detatch at least one end of the shocks, collapse it all the way to engage the adjuster and then twist CW or CCW. I don't remember.
