These shock absorbers are really good. Swapped a Rancho 5000 set with these and the drivability difference isn't noticeable until you hitch a trailer, then they really shine. It's quiet all the time, nothing creaks or smacks, I bought it used. They look very heavy and are well made. The install instructions say they are for standard height vehicles, but I installed 2" jack blocks in the back of my truck and they work fine, no extra brackets or anything.
