Description
6.4L Powerstroke ARP Main Stud Kit
Upgrade your 6.4L Powerstroke engine with the ARP Main Stud Kit. This kit is designed specifically for Ford Powerstroke 6.4L engines. ARP recommends using main studs instead of bolts because studs provide more accurate torque readings. Unlike bolts, studs do not twist into the block. This allows all clamping forces to be applied along one axis, which improves engine stability and performance.
Using ARP main studs reduces the risk of main cap walk and fretting. These issues can cause engine damage over time. The kit includes high-quality components such as hardened, parallel-ground washers and nuts. ARP manufactures the studs from 8740 chrome-moly steel. They heat-treat the studs in-house to reach a tensile strength of 200,000 PSI. After heat treatment, the J-form threads are rolled to increase strength. As a result, these fasteners are over 2000% stronger than standard fasteners.
Whether you are rebuilding your engine or upgrading for better performance, installing ARP main studs helps keep your engine properly aligned. They protect your engine under extreme conditions. Trust ARP’s quality and strength. These studs maximize your engine’s longevity and performance.
