Hey everyone,

Just wondering, can anyone verify for me if the ARB diff covers come with grade 8 hardware?

Im pretty sure, i just want to make 100% sure.

Thanks so much!

Sean

 

anyone????

 

Ok Ill say it, what is grade 8 hardware

 

the bolts that hold the diff cover into the diff...some come with grade 5 some come with grade 8...grade 8 is stronger...was just curious.

 

Does it indicate the grade on the head of the bolt?

 

In a manner of speaking...

I got mine from northridge4x4 and they came with grade 8 and Lubelockers. If you order these, ignore instructions.
Ask Dave for proper torq specs.
If you follow ARB specs, you will break some heads.

They will take a serious beating, so get them regardless.

 

i am getting the combo set from dave. and he just wasnt 100% sure if they were grade 8. i am having a shop put em on for me...so if they ruin it its their fault. haha

 

Just received mine from Dave and yes they come with grade 8 bolts. I went ahead and painted mine to match my jeep though.

 

Just wondering, is grade 8 really necessry on diff covers, I mean most impacts are compression not tension. I just don't know if it really matters?
