that is a good rule for framed jeeps you can use less bolts

but with a Cherokee and the thin frame you need more bolts and a grater surface aria to create strength

 

yeah i defiantly agree with you here but i still think the 8's are going to be better in a situation where it could see a load or be used as a recovery point and see quick jerks to get unstuck. i would rather be safe then sorry

 

man, i don't know if people just don't listen, or what it is with the info going on around here. not directing that at you, but for the third time. grade 5 bolts are mandatory for most organizations regarding tow points, not minimum, grade 8 and you won't pass inspection. and what manufacturer uses grade 8 bolts all over the suspension?

and like someone already said regarding them being better. thats not it either. grade 8 has a higher tensile strength than grade 5. but like mike37 said, harder isn't better always.

for his application he's fine with what he's got. grade 8 is overkill, but will not be dangerous either, grade 8 is considered dangerous on tow points because they do not stretch. on a tow point you can see a grade 5 bolt stretch before it breaks, and know to stop or replace the bolts. if grade 8 reaches its breaking point it will show no signs untill it snaps.

and who on here has seen either bolts break under load? used properly i have to add.

 

no mater what bolt you use the frame is not strong enough to warrant a grade 8

a grade 5 will pull through the frame before it brakes

 

why does every bumper manufacture out there supplies or offer grade 8 with there product. conspiracy maybe

 

marketing

 

^ beat me to it, exactly. and i'm not sure i've seen every bumper manufacturer say they use grade8 bolts. and secondly, it is for people out there with this misconception, it makes it seem more appealing, oooohh grade 8 bolts, must be a good one.

but i'm really more concerned about the statement that grade 5 bolts are not for load bearing situations. just plane wrong. i guess all the organizations and clubs are in on a conspiracy requiring grade 5

 

Awesome, it's about tied up....I still can't decide. I see both sides of the issue, and that's why I started this poll. I was hoping there would be a more defined concensus, more time I suppose, thanks so far guys!!

 

its not really

the way you have it set up it really makes no difference 5 or 8

the thing that would make the biggest difference is larger thicker washers
or a full size bearing plate

 

Yeah, the washer are pretty much cheese. I'll at least be picking up better washers.

 

Exactly. You can see the wear and tear before a critical failure. Warnings are much better than surprises.

 

8 all the way. why have a weak link?

The bolt that holds the trackbar to the axle on our jeeps is a grade 10.9. The trackbar pulls against it tring to snap it.

Use grade 8.

 

^yep nhegl, and the plate is the best idea. i made one for my rear tow hook, and welded the nuts to it, so i just slid the plate in, and bolt up the hook, and bracket that tied into two other points.

man, i give up, how is a grade 5 bolt a weak link.

 

thats one bolt compared to 10
apple and oranges
