I run the Fox 2.0 res shocks on my JK with teraflex coils. It's a stiff ride, but I prefer a sharper on road handling experience. It isn't so stiff that it's uncomfortable, and the roads up here in central NY are awful. On the trail they're great so far. Had no trouble in rocks, plenty of flex and they absorbed a few really hard drop offs (I'm still learning to be gentle lol)
It's such a subjective topic when we discuss Springs and shocks, but both king and Fox are proven products. I don't see how you'd go wrong with either.
