MAIN STUD KIT

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
stand-off 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 2000% stronger than
others.
