That is what I was doing. We were jumping the New Orleans levees. Everthing was fine until brother-in-law tried and landed from about 20 feet up straight on the rear bumper. The mounts held, bumper snapped and three of the four rear shocks had their bottom screws ripped out of my RPM arms.
EW i didn't know the shocks bottom mount screw came out! Did you have them nutted aswell as threaded?
