I'm worried my balljoint bolts might break 91 gmc jimmy 4.3l v6?

the bolts that came with the bjs are fine...they cant give you bolts that are not strong enough.LIABILITY ISSUES make sure the holes in the control arms are flat and smooth from chistle marks and tighten the new bolts very snug but not cranked down on hard...as someone who has done countless numbers of them they are tightened to 17 foot pouns and the castle nut is tightened to 61 foot pounds
