What is the tensile strength of these ARP head studs?

These ARP Pro Action head studs are made from 8740 chromoly steel and are heat-treated to a tensile strength of 200,000 psi. This ensures they can withstand the high clamping forces required in performance engine builds.

Are the nuts and washers included with this head stud kit?

Yes, this kit includes the necessary 12-point nuts and hardened parallel washers. These components are also made from high-strength materials to match the studs.

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

Head studs generally provide more consistent and accurate clamping force on the cylinder head gasket. This improved clamping helps prevent leaks and ensures the gasket stays sealed, especially in high-performance applications where cylinder pressures are higher.

Product Details

If you're rebuilding the top end of your Small Block Chevy, ARP's Pro Action 14A 12-point head stud kit is a solid choice. This kit is designed to provide a more secure and consistent clamping force for your cylinder heads compared to stock head bolts, which is crucial for preventing leaks and ensuring proper gasket seal under high performance conditions.

ARP uses premium 8740 chromoly steel for these studs, heat-treated to a tensile strength of 200,000 psi. The 12-point nuts and washers are also made from high-strength materials, ensuring they can handle the torque and stress of performance engine builds. The kit includes hardened parallel washers that help distribute the load evenly, preventing the stud from digging into the head or block surface. This attention to detail in materials and design helps ensure a reliable seal for your engine.

This kit is specifically for Small Block Chevy engines and is a popular upgrade when you're looking for improved reliability and performance from your engine build. Always refer to the manufacturer's installation instructions for proper torque sequences and specifications.
