What is the tensile strength of the ARP2000 alloy used in these head studs?

The ARP2000 alloy used in this head stud kit has a tensile strength of 220,000 psi. This high tensile strength helps ensure the studs can withstand significant clamping forces.

Why are ARP head studs better than factory head bolts?

ARP head studs offer more consistent clamping force and are less prone to stretching under high cylinder pressures compared to factory head bolts. This helps maintain a reliable seal for the cylinder heads.

What is the advantage of the 12-point external wrenching head?

The 12-point external wrenching head makes installation and removal of the studs easier, especially in confined engine spaces. It allows for better access with common socket sizes.

Product Details

The ARP2000 alloy used in these head studs offers a tensile strength of 220,000 psi, making them a strong choice for securing your Toyota 5.7L 3UR-FE engine's cylinder heads. When you're rebuilding the top end or dealing with higher cylinder pressures, factory head bolts can sometimes stretch, leading to gasket leaks. ARP head studs provide a more consistent clamping force, helping to keep your heads sealed under demanding conditions.

These studs feature a 12-point external wrenching head, which makes them easier to install and remove compared to traditional hex heads, especially in tight engine bays. ARP includes parallel-ground washers and high-performance nuts with each kit. The threads are rolled after heat-treating, which ARP states makes them up to 2000% stronger than threads that are ground before heat-treating. This process also helps to reduce fatigue and increase durability.

For proper installation, it's recommended to consult ARP's detailed instructions, as they will outline the specific torque-to-yield sequences and any necessary preparation steps for your engine. This kit is designed to fit Toyota 5.7L 3UR-FE engines.
