ARP Diesel Main Stud Kit 247-5402

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.  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.
