    Anyone know what the strength difference really is between 5/8" and 3/4" bolts? I'm looking at what misalignment spacers and bolts to run in my 4 link and considering this issue. I'm thinking a 5/8" bolt mounted well in doubler shear, the heim joint will brake before the bolt does. My thought process could be wrong, but thats what I'm thinking. Thoughts on this?

    I would think it would be proportional to the difference in cross section of the two, assuming the fasteners are made of the same material. (i'm guessing)

    We're talking a shear load right? Jeez, I think they rate bolts in psi. and I'm not near smart enough to try and figure that out, but I have an structural engineering book here so... no help.
    Ok try these links, I think they'll give you an Idea.
