where did you find lowered leafsprings for an explorer? or were you planning on removing a leaf or two from stock?
if you're worried about the axle pin, or the block itself breaking, check out AIM industries extruded aluminum blocks.
they claim they can handle 100,000 lbs. of pressure without breaking, while a cast metal block can actualy break with less than 2000 lbs.
"extruded block has a cnc machined steel pin, and the pinion angle is built into the block. Extruded steel forms a compression fit to the curve of your leafspring, forming a tight fit that will not loosen."
they don't cost much more than blocks from an autoparts store like autozone and they sound like a much better product for the money.
if AIM can't get you the proper u-bolts, here's another option. a guy at Seymour Alignment told me there is a place here in Indiana that he can order custom sized u-bolts from. You might give them a call (Seymour Alignment) at 812-522-6536. Seymour is less than an hour from southside indy. if you have them get the u-bolts, when you drive down to pick them up, you might as well have them put them on, too. i didn't lower the rear of my ex myself b/c the bolts were so corroded, they only charged me $20 to do the job.
