Re: Head bolt final outcome



I think they just feel they are not a product that perhaps has as much quality control as it needs. 

Regarding 'hylmar', is that a real product? So no I didn't use that. Actually I use nothing on the composite but will use either the copper coat or maybe the Mopar stuff IF I run across it.

Rich,

This is good info...thanks.

Is their concern that they are Chinese and not actually grade 8 bolts??

I'll be looking for these soon as well and I'm NOT paying 800-1200 for
custom ARP's!!!
