Mine have taken a pounding... Been on there for about 4-5 years- Left a bunch of paint all over and had lost a bolt in Moab but my rockers are intact. I like the way their new ones look a little more but either way, Ive been extremely pleased with all my JCR products.

 

This isn't really anything against them since it's mostly my fault, but the only thing I don't like is the design of the stage-3 where the door guards angle up and only clear the doors by very little. I smashed the crap out of mine on the Rubicon and actually pushed the rocker panel up and they ended up dragging. I cut off the tubes and re-welded straight.
