There are many important reasons to use ARP Main Bolt Kits for your Chrysler, Dodge, or Desoto hemi, including the elimination of main cap walk and fretting, as well as truer torque settings. The ARP main bolt kits are manufactured in ARP’s own factory using the best materials, processes, designs and engineering.

Every ARP main bolt kit exceeds the most stringent aerospace specifications. All kits come complete with hardened parallel-ground washers.

  The ARP Chrysler Main Bolt Kits 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  significantly stronger than other manufacturers.Don’t settle for anything less than the best. Insist on genuine ARP bolts from TR Waters Early Hemi Parts –   you’ll find the ARP name stamped right on the end!   Feel free to contact me with any questions.


I recommends the use of ARP main bolts whenever possible over 50 year old factory parts for several key reasons. One is the superior manufacturing process now in place. Why take a chance on an old part that was supplied 50 years ago by the lowest bidder?  Another reason to use new quality ARP bolts. They haven’t been subjected to years and years of unknown heat and stress cycles.

Do not confuse these bolts with small block Mopar bolts, which can bottom out before reaching the correct torque. These are the real deal.
