What is the tensile strength of these ARP head studs?

These ARP head studs are made from ARP 8740 chromoly steel and are heat-treated to achieve a tensile strength of 200,000 psi. This high strength is crucial for maintaining a secure seal under significant engine loads.

What makes 12-point nuts beneficial for head studs?

The 12-point nuts provide more points of contact for your socket compared to standard 6-point nuts. This allows for easier access and torquing, especially in tight engine compartments where wrench clearance can be limited.

Are these studs suitable for high-performance engine builds?

Yes, ARP head studs are a popular choice for high-performance and racing applications due to their superior strength and ability to maintain consistent clamping force. They are designed to handle the increased stresses found in modified engines.

Product Details

This kit gives you a full set of ARP SB Dart 18A 12-point head studs, along with the necessary nuts and washers, to securely fasten your cylinder heads to the engine block. These studs are designed for the specific needs of SB Dart 18A engine applications, offering a more robust and consistent clamping force than standard bolts.

ARP is well-known for making strong engine fasteners, and these head studs are no exception. They are made from a proprietary ARP 8740 chromoly steel, heat-treated to achieve a tensile strength of 200,000 psi. This means they can handle the high clamping loads required to keep your cylinder heads sealed under demanding conditions, preventing leaks and ensuring proper engine performance. The 12-point nuts make them easier to torque down, especially in tight engine bays, compared to traditional hex nuts.

When you're rebuilding or upgrading an engine, especially one like the SB Dart 18A where reliability is key, using quality head studs is a critical step. This kit is a solid option for ensuring your cylinder head installation is secure and long-lasting.
