What is the point of those? Are they rocker rails or just for looks? I know they are Mopar.

From what I see in the last (bottom) picture, the rails are too high up the side of the KJ to protect the bottom part of the rocker panel. I'm sure those rails can offer side impact protection, but don't you get more impacts from underneath?
I'd really love a good combination rock/step rail, but I don't see how we can have both be functional at the same time. Some tube-type step rails extend down far enough for the vehicle to rest on them, but can they handle the weight? And don't they reduce your ground clearance? I see too many KJs with the step rails, and they rails look like they're only 5" off the ground.
