Does anyone know what size ubolt i need to replace the old ones?
Ive looked thru the tech section and cant find it. not saying its not there, just cant find it.

Thanks in advance

I don't know the answer to your question... But I was gonna mention that you might want to think about new shocks while you were under there. Just in case you hadn't... I forgot and now have to go back and do that.

width and length..
I know the leaf spring pack is 2.5 but i have seen some u-bolts on line listing as 2.75 and 2.5 for the bronco.

The stock Explorer u-bolts are 3 1/4" wide and 7" tall with about 2 1/2" of threads. The Explorer housing has 3 1/4" tubes, the B2 has 2 3/4" tubes.
You should measure the diameter of your tube, add the height of the spring perch and the thickness of the spring pack plus about 1 1/2" to get the length you need.
Looking at my 86 B2, I think the u-bolts will work, mine stick up about 1" above the nut.

Thanks Ray, Im not putting the 8.8 in so its the stock but that does help. Im going to go with the 2.75. and 7.5 if i need to cut thats ok.
