I recently drove over some rough road (steep downhill with undulating surface) and I had a surprise when the lower control arm hit the road. Needless to say it upset the truck in the middle of a corner and it was violent enough for my passenger to comment. The damage is cosmetic, but did expose that the lowest point of the suspension is the shock itself. It took a chunk out of the eyelet and scraped the mounting bars/bracket.

My takeaway is that you really need to run a taller tire than I have (27"), and be very aware of the road. If I had been driving more spiritedly, I could have lost control of the truck.
This is the limitation of the stock crossmember/control arm location setup. The only way to get a long enough shock/spring is to raise or lower the mounting location of the shock itself. Seeing that there's not much room for raising the shock location, lower is the easier option.
