The OEM washer is only .121" thick vs the ARP at .117". So you are talking only .004" difference between the two in thickness The ARP are .995" OD vs OEM that are .978". So the ARP are .017" bigger Also the ARP are chromoly and hardened. I am not sure on the OEM's. So I will personally still stick with the ARP over the OEM because they are bigger in diameter.
