I have only seen one episode where "supposedly" the bolts have failed on a body lift due to an accident, on the internet that is...and you aren't even certain that the bolts failed. I have seen a couple hwy speed accidents with fullsize trucks with 3" body lifts and they didn't shift one bit. I have seen plenty of rollovers with trucks and jeeps with body lifts, and never a problem. This is all what I saw, not read or heard about from someone who knows someone who knows.....
A little jeep with a body lift with so many mounting points body to frame will not be affected by stress on bolts. Full size trucks will fill their truck beds up all day with 3" body lifts and putz around and never have trouble with mounts or bolts breaking. I know people who beat the living piss outta their rigs and not one has ever seen a body lift failure except fan shroud relocation brackets and small stuff like that. Usually install errors. If there have been failures due to body lifts I would love to learn about them.
My old 01 Ram had 3" body and I filled the bed and never had sheering issues when breaking or accelerating. My old Toyota was fine too, I beat the crap out of that tough little truck, it had a body lift.
I choose not to have a body lift on my TJ since I don't need one, and I don't like the little gap between the body and frame. But those are personal choices.
