What is the main advantage of using main studs over main bolts?

Main studs offer a more consistent and stronger clamping force compared to stock bolts. This is because studs allow for a more accurate stretch measurement, which helps prevent main cap walk under high stress conditions.

What material are these ARP main studs made from?

These studs are manufactured from ARP's proprietary 8740 chromoly steel, which is heat-treated to achieve a tensile strength of 200,000 psi.

Does this kit include everything needed for installation?

This kit includes the main studs, nuts, and washers. It is recommended to refer to ARP's installation instructions for specific lubricant and torque-down procedures.

Product Details

If you're rebuilding the bottom end of your Small Block Chevy, especially for a performance application, securing the main caps is critical. This ARP main stud kit uses 1/2 inch straps to provide a much stronger and more consistent clamping force than stock bolts. This helps prevent cap walk and ensures your crankshaft stays properly supported under load.

ARP is well-known for making strong, reliable engine hardware, and this kit is no exception. The studs are made from ARP's proprietary 8740 chromoly steel, heat-treated to achieve a tensile strength of 200,000 psi. This means they can handle the increased stress and torque that comes with a performance engine build. The kit includes the necessary nuts and washers, all made to ARP's high standards.

When installing these studs, remember to follow ARP's recommended torque-down procedures, which typically involve a series of steps with lubricant to achieve the correct stretch and clamping force. This attention to detail ensures the studs perform as intended and contribute to a well-built, durable engine.
