Simple rear hub spacer question

[glowbox]

When installing the longer 10mm bolts is grade 8.8 going to be strong enough or do I need the hardened bolts (grade 10.9 and hard to find)

i think the grade 8.8 should be fine. i have no experience in this field but i used grade 8 on everything on my jeep (to include the roll cage) and it holds up fine. My jeep is mainly used offroad and a ton of stress is put on my parts

I'm using 8.8 on my 10mm shims. Only had them for about 2 weeks but I haven't had any problems with them.
