Colours might differ slightly between the monitor you view and the actual part. Please do keep in mind that used parts can have some small wearing marks. All details of this part are shown in photos. The images are of the actual item you will receive. Parallel-ground, hardened washers are included with each kit. The threads are rolled after heat-treating, which makes them about 1000% longer fatigue life than most main bolts, which are threaded prior to heat-treating. Forged from 8740 chrome moly, all bolts feature generous under-head radius and rolled threads for the utmost reliability.
#6.7 CUMMINS REAR MAIN SEAL PART NUMBER PROFESSIONAL#
Main Bolts Far superior to any other main bolt kit offered for use in competition engines, ARP main bolts are designed to meet the exacting standards and demands of professional engine builders. 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 1000% stronger than others. 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 high quality nuts. Main Studs 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.
