Single shear is not fine for a rock crawler. Let us know how long they last before the brackets rip off.
LOL ..... IMHO a harsh post like that makes you look like a smartass
but i agree: i personally would feel better when them nice big Kings would be supported by shear force and not relay on the bending strength of the bolt (or at least i would replace the 1/2" reducer bushings and run 5/8" bolts together with spacers that are welded to the base plate)
but hey...this is the internet: 5 peeps = 7 opinions

Paul, i hear ya on the easy access.... on my cars there is usually so much stuff and everything is crowded so tight together that you have to remove the bypass shocks to access the pre-load ring on the coilovers

....
a pain in the rear ... but at least after you finally set your ride height there is no need to remove them anymore
