ARP 185-5401 - Main Stud Kit

Description

You’ll note that the studs have a radiused bullet nose that serves to locate the pan rails, then allow the nuts to be easily installed without the worry of cross-threading. All kits come complete with hardened parallel-ground washers and high quality nuts. 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. They’re designed to make it as easy as possible to install a pan and seal it properly. 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. All kits come complete with hardened parallel-ground washers and nuts. The engineers at ARP spent quite a bit of time developing these highly effective, unique oil pan studs. For those who prefer bolts, ARP’s got you covered, too. The studs are manufactured from 8740 Chromoly 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.
