some prebuild engineering went into that for sure ogre.
-c notch built sturdy and reinforced up to the underside of the bed wood
-frame boxed for added strength in area of notch
-uses stock spring pack, however modified, with teflon anti-squeak liners and stock hangers.
-beehive shaped (stepped urethane?) bump stop positioned to contact axle before axle comes very close to contacting the frame. this allows the bump stop some suspension travel time in order to absorb some of the shock before the axle contact the frame. I have seen stock vehicles where that snubber is even closer to the contact point at ride height, like 3/4" of suspension travel before contacting the bump stop. the vehicle rode quite nicely and the snubber did not wear out like one would think
-stab bar positioned such that the front attachment parts are not going to pick up every stray plastic bag or skunk wandering across the road
-track width allows non special order wheels
-axle has useable stock brakes and park brake is not a big pain to set up linkage for
-axle flip uses readily available parts. spring pad is simply a part from a trailer axle shop that can be squashed in place when the u bolts are tightened up, the driveline angles can be matched with the pad able to move on the axle then it can be welded in place on the axle once the final checks have been done to ensure correct centering and driveline pinion angle
-sort of the best one could do without raising the bed floor. this allows the use of a stock bed. it uses a more normal daily driver tire size but if one really needed huge tires some mini tubs could be added. not sure on space left over between inside sidewall of tire and frame or box.
if axle wrap or wheel hop is a worry with possibly softer spring pack then there are ways around that too without modifying the existing set up, a simple bolt on part.
