steel and have 190000 psi tensile strength rating. They are

There are many important reasons to use ARP main stud
kits, including the elimination of main cap walk and fretting, as
well as protecting the threads in your engine block. All kits come
complete with hardened parallel-ground washers and high quality
nuts. Some applications have provisions for mounting windage trays
and have specially designed standoff studs with serrated lock nuts
to position the windage tray and lock it securely in place. The
studs are manufactured from 8740 chrome moly steel, heat-treated
in-house to 200,000 psi tensile strength, and precision J-form
threads rolled after heat-treat to create a fastener that has
threads 1000% stronger than others.
Far superior to any other main bolt kit offered for use in
competition engines, ARP main bolts are designed to
meet the exacting standards and demands of professional engine
builders. Forged from 8740 chrome moly, all bolts feature generous
under-head radius and rolled threads for the utmost reliability.
The threads are rolled after heat-treating, which makes them about
1000% longer fatigue life than most main bolts, which are threaded
prior to heat-treating. Available in the popular High Performance
Series, which, at a nominal rating of 180,000 psi, is a premium
replacement for OEM fasteners, or the 200,000 psi
nominal rated Pro Series, application-specific main bolts with
reduced wrenching head and are designed for use in competition
applications. Parallel-ground, hardened washers are included with
Designed to fit with windage tray.
