body lift question re: bolts

[55Willy]

Should I run the grade 5's it came with or upgrade to grade 8's?

Grade 5 should be fine...what size body lift?

Grade 5 will be fine, it's already strong enough that the backup nut will break before the bolt.

all the articles I read about this and all the kits include grade 5 bolts.. not because they are cheaper( which they are by a couple of cents) but beacause they apparently have more stretch before breaking,, 8s are stronger in tensile but not shear,,, so Ive been told but Im no expert,,,, /forums/images/graemlins/confused.gif
