With the ARP BMW S63 Head Stud Kit, you can securely tune up the boost on your S63 engine without worrying about the cylinder heads lifting. Specifically designed for the turbocharged V-8 S63 engines found in high-performance models such as F10 M5, F90 M5, F12 M6, F15 X5M, F16 X6M and F13 M6. ARP Part numbers: 201-4702, 201-4703.

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. Our ARP Head Studs are designed to be stronger than factory bolts, ensuring your race engine stays together even under extreme conditions.

The ARP Custom Age 625+ BMW S63 Head Stud Kit is made from a material with a tensile strength of 260 ksi, 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 S63 builds.

Our Oversized Kit option utilizes ARP's proprietary Custom Age 625+ material option combined with specialized insert washers for ultra-high boost applications. Please note that this kit requires that the cylinder head be clearanced and the engine block to be machined for the installation of insert washers.

Please note: After initial assembly, it is necessary to allow the engine to complete a full heat cycle, then re-torque your head studs to spec. This means allowing the engine to warm up to its normal operating temperature, remain at operating temperature for several minutes to ensure each component is uniformly heated, then turned off and cooled completely to ambient temperature.
