Moser Engineering® 7116 - Main Cap 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. Every main stud kit exceeds the most stringent aerospace specifications, and come complete with hardened parallel-ground washers and aerospace quality nuts. J-form threads are rolled after heat-treat to create a fastener that has threads 1000% stronger than others. Be aware that, although ARP produces both studs and bolts, they recommend the use of main studs over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don't twist into the block. All clamping forces are on one axis. They also allow for easier engine assembly and proper alignment of caps every time. Manufactured from 8740 chrome moly steel Rated at 200,000 PSI, which is considerably stronger than Grade 8 hardware Rolled J-form threads are 1000% stronger than other threads
