What material is this main stud kit made from?

This kit is manufactured from ARP 2000 material. It's a heat-treated alloy known for its improved tensile strength, making it a strong choice for performance engine builds.

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

Main studs provide more consistent clamping force on the main bearing caps compared to torque-to-yield bolts. This helps prevent cap walk and ensures proper crankshaft alignment, especially under higher stress.

Yes, this kit comes with the necessary studs, nuts, and washers for installation. Always refer to ARP's specific installation instructions for any additional requirements.

Product Details

These ARP main stud kits are made from ARP 2000 material, which is a strong, heat-treated alloy that offers improved tensile strength over standard ARP 100 material. This makes them a solid choice for rebuilding or modifying your small block Chevy engine. Using main studs instead of bolts helps to keep your main caps securely in place under high stress, which is crucial for engine longevity and performance. The kit includes the necessary studs, nuts, and washers, all manufactured to ARP's exacting standards for a reliable installation.

When you're rebuilding the bottom end of your small block Chevy, especially if you plan on adding more power, using main studs is a smart move. They provide a more consistent clamping force on the main bearing caps compared to torque-to-yield bolts, which is important for preventing cap walk and maintaining proper crankshaft alignment. This kit is designed specifically for 2-bolt main blocks, ensuring a direct fit for your application. ARP has been a trusted name in performance engine components for a long time, and this kit reflects their commitment to well-built parts.
