Within any brand there are different levels of quality and shock "strength". While they don't have anything to do with ride height (aren't supposed to anyway, air shocks are a Band aid) the "oe equivalent" at the bottom of the line usually isn't.
Myself, I've tried em all over the years, threw the new kybs that I had on one of my Dakotas in the trash after a couple of months. Went back to my old stand by, Gabriel ultra. If those are available that's what I use on everything. Last I checked they run about $36-40 each at useless zone, I find them for about 1/2 of that between rock auto or Amazon
