Have driven them on 4WD with a full load and none have broken! I've installed two other types from other brands that make a lot of urethane mounts and parts and both broke. One was almost the same in design, but bigger and red, and it didn't run 20 miles on the trail. I emailed the other manufacturer and told them the first ones were broken and asked if they had any suggestions but apparently they ignored me. (They rhyme on a synergistic dimension) I don't care that they're broken as long as they help me, answer me, and give me advice.
