ARP BMW S58 U/C 12pt head stud kit

BMW S58 Head Stud Kit - ARP 201-4705

The ARP Head Stud Kit for the BMW S58 engine is a must-have upgrade for high-performance builds and forced induction applications. Designed to handle the extreme cylinder pressures generated by the twin-turbocharged 3.0L inline-six found in the G80 M3, G82 M4, and G87 M2, these studs offer superior clamping force and long-term reliability over factory torque-to-yield bolts. Manufactured from premium ARP2000 or Custom Age 625+ alloy (depending on configuration), they feature precision-rolled threads and are heat-treated for maximum strength, making them ideal for street, track, and full race applications where head lift and sealing integrity are a concern.
