I am finally putting to use the high clearance ubolt spring plates that some forum members put together with a group order. Honestly, its taken me 2 years to put them to use as I have found them more hassle than possibly worth. In addition to my suck-o-la welding (took some attempts and way too much time to get the gussets reasonably acceptable - I don't know what it would cost to get them pre-assembled with the gussets, but I would easily pay it), a shock mount solution is needed if replacing the OEM style. The best plan is probably to mount the shock on the axle tube, but given how short that makes the shock and limits the travel, using a taller top shock tower is needed. I wasn't prepared to do all that - so I eventually welded some shock mounts on the bottom of the base plate, trying to replicate the OEM location. This of course gives up the ground clearance the plates are designed to improve - but the only piece hanging low is the shock mount, and the ubolt ends/nuts are protected up out of the way. In addition, the low shock mount required some minor modification (more cutting, welding and grinding) for a bit of clearance. The pic is with the axle in full droop (hanging), so the shock position is most vertical and clearance is tightest. With weight on the springs, the axle shifts back and the shock body moves away from the plate - its tight, possibly too tight and the rubber shock bushing will allow a bit too much movement and some contact will be made. Its also possible the exposed shock mount will get ripped off in the rocks - at this point, that will be the end of them and it'll get some skid style spring plates.
I don't know that I would use these again - certainly not with a shock mount on it. If I had an exposed frame and building new taller shock towers, then maybe. As I posted just a week or two back, I chose to go with the skid style plates on the front as I really didn't want to deal with grinding on the passenger center tube where the larger inner ubolt goes over the center housing. I still have a front pair that can go with this rear pair if I ever get around to building that trail rig I always dream about.....but I think the 2nd complete set of 4 I have is going up for sale - I just sold you all on how awesome they are right?
