What dimension u-bolts do I need for a 2" block?

i thought they were just universal that you cut to length?

I had mine made by a local spring shop. The Autozone/Advance ones are grade 5 garbage. The dimensions I used were 7/16" thick x 3" inner leg to leg x 20" leg length and of course round top and grade 8. Those were for 2" lowering blocks.

There are different diameter axle tubes and thus different sizes of u bolts. The shop that made mine just asked what kind of truck I had. I had to tell them that I had the axle from an Isuzu rodeo and they made me U bolts based on that.

I just winged it and got one that fit.

I think our trucks are a pretty common size. Its not a giant 1 ton or a weenie little car axle or anything.

Well the parts house had 10 different u bolts. All varying in length and width. I didnt know which to grab.

What the spec ( S ) for original U bolts for 86 hardbody, the truck is to low to come out of my garage and i dont wanna damage anything and pay. Basically im trying to raise back to normal stock height cause here in hawaii we do what you would call a safety check and the truck has to be factory stock...
