Alternators that come loose are a pain, which is why these super tough bolts were developed by ARP (your choice of polished stainless or chrome moly steel ARP 300 both rated 170,000 psi).
The stainless has the added advantage of being resistant to rust and corrosion.
Alternator Stud Kit: Strange as it may seem, many races have been lost in endurance competition, oval track, and off-road due to the failure of the OEM alternator stud and the subsequent loss of electrical power.
To prevent this from ever happening, conscientious engine builders rely on ARP's bulletproof alternator studs.
Made from a premium grade 8740 chrome moly steel alloy, they are heat-treated to a nominal tensile strength of 200,000 psi.
They are very rigid and will not bend under the stress of competition, eliminating problems with alternator pulley alignment.
