Those are some pretty heavy duty Monroe shocks (don't remember for what) but as long as the mounts don't bind much they work just fine. I have tried shocks that have a stud at the top at approximately the same angle as what is pictured above and it does not work as well (binds / bends to much). As for ride quality it is not bad considering how STIFF the front springs are.
My daughters truck has the shocks pretty much set up the same way with RE-6 bags and it is a blast to drive - very smooth! Only difference is the LCA mount is welded to the LCA.
FYI, the rear shocks on my truck are mounted almost flat and they work just fine
