[QUOTE="TreeClimber, post: 1474203, member: 16101"] The tasks I asked for help on, were related to the abuse anticipated. When the TJ was first built, we notched the rear frame, and recessed the springs up and back. This allowed for a wheelbase stretch, and I could keep the lift springs the same, front to back. As the Spring-Plate was moved backwards, the frame rails curve down, so the had to be notched up, to compensate for the loss in height, no longer being at the apex of the arch. This was all fine and dandy, because the frame on a TJ doesn't really do anything, except hold up the fuel tank (as all the suspension links come from the middle of the frame, and there's nothing at the rear). However, since I'm now going to be towing a loaded dump truck, having a really strong rear bumper becomes important, which also neccessitated a strong rear frame. So the fuel tank was removed, as was the rear crossmember (where the shocks would normally mount), and the whole rear section was plated, and the rear bumper mounting holes were reinforced. Then everything was rewelded back. You can also see the shock, which were switched from behind the axle, to in front. The cage was already a stout, well built cage. However there was insufficient headroom to fit helmets (which also means probably a head-buster in a rollover), so the rear center bar was raised almost 3 inches, and new X-bracing, and new spreaders. Also mounted the seats to the cage. [/QUOTE]
