200,000 psi tensile strength puts these ARP studs well above stock hardware. If you're looking to build a serious engine, especially one that will see a lot of abuse or high horsepower, you need hardware that can handle the stress. These ARP main studs are forged from high-strength 8740 chromoly steel, giving them a tensile strength of 200,000 psi. This means they're incredibly strong and resistant to stretching under extreme cylinder pressure, which is crucial for keeping your crankshaft bearings properly seated and preventing cap walk. They are heat-treated and then polished to a smooth finish, reducing stress risers and improving fatigue life. ARP includes their special Perma-Loc™ washers, which are designed to prevent the nuts from backing off under vibration, a common issue in high-performance applications.

When you're building an engine that needs to perform, using stock bolts for the main caps just isn't going to cut it. These ARP main studs are a popular choice for a reason: they offer a significant upgrade in strength and reliability over factory bolts. The kit comes with everything you need, including the studs, nuts, washers, and a packet of their ARP Ultra-Torque™ assembly lubricant, which is essential for achieving accurate torque readings. Following the manufacturer's installation instructions is key to ensuring these studs perform as intended and keep your bottom end together under load.
