These are locals guys and both were running UD60's. One made it out fine and the other broke plug welds in both front and rear and spun both pumpkins (as he described). The guy that spun both killed the rear driveshaft and bent front coilovers. They do wheel the piss on out their Jeep's but I don't know of one local guy that hasn't had an issue with the UD60's which is why I switched to Dynatrac. I believe both (I know at least one) have winches that keep their front ends down.
The welds on these things, plugs and brackets, are a QC nightmare and seem to be hit or miss on the quality. All the local guys seem to have issues, another guy snapped the trac bar bracket off but I see others on the forums that haven't had any problems...tickin timebombs is the thought that comes to my mind. Some are now buying them, adding trusses, drilling out plugs and rewelding, gusseting and adding weld to brackets, adding weld to the tube and pumpkin mating surface.
I unfortunately fell for the "it's cheaper" deal and got the UD60 rear. I'll be trussing (had to for the RK 3 link rear anyways), gusseting brackets, and welding the tube/pumpkin at the join. XD60 is on order for the front so made a mistake but corrected my thinking before it was too late.
