BMW Head Stud Kit 12pt 2.5L/3.0L/3.2L Inline 6

The ARP BMW Head Stud Kit 12pt 2.5L/3.0L/3.2L Inline 6 is a professional-grade fastening solution specifically designed for BMW inline-six engines, particularly the M50, M52, and S50 powerplants. This kit is ideal for those upgrading from factory bolts to prevent head gasket failure and cylinder head lift.

Manufactured from 8740 chromoly steel and heat-treated to exact specifications, the ARP studs feature a 12-point socket head design that provides superior grip and reduces fastener rounding. The kit includes studs, washers, nuts, and ARP's proprietary assembly lubricant, ensuring consistent torque-to-clamp-load values for reliable engine builds.

This stud kit fits all BMW 2.5L, 3.0L, and 3.2L inline-six configurations, including the M50/M52 and S50/S52 variants found in E30, E36, E46, and Z3 platforms. Installation requires removal of the cylinder head, making it a critical component for high-performance builds.
