ARP Head Stud Kit, BMW / Toyota B58

This ARP2000 Head Stud Kit 203-4705 is designed for the turbocharged inline 6-cylinder B58 engines found in various BMW chassis and the Toyota GR Supra A90/A91.  As you increase the power output of your engine beyond its factory specifications, the head and block may start to separate, causing factory bolts to stretch and fail. ARP Head Studs are stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. 

The Custom Age 625+ option 203-4706 is a kit made from a material that has a tensile strength of 260 ksi, which is substantially higher than the 190 ksi of the ARP 2000 head stud. It's an ideal choice for individuals who want to push the limits of their B58 builds and require a stronger head stud.
