ARP 201-4701 BMW Head Stud Kit - B58 3.0L 12-Point ARP2000

The ARP 201-4701 head stud kit is engineered specifically for the BMW B58 3.0L turbocharged 6-cylinder engine, providing superior clamping force and reliability for high-performance and forced induction applications. This complete kit features premium ARP2000 material studs with 12-point heads for easier installation and re-torquing without valvetrain removal.

Key Features:

• ARP2000 material construction with 220,000 psi tensile strength rating
• 12-point head design for improved wrench access and ease of installation
• Includes 14 studs with recommended torque specification of 122 Nm
• Thread-rolled after heat treatment for superior fatigue strength
• Centerless ground for precise tolerances and perfect head alignment
• Reusable design versus factory torque-to-yield head bolts
• Ideal for turbocharged engines requiring increased clamping force

ARP head studs provide more accurate and consistent torque loading compared to factory bolts. The studs are installed in a relaxed mode and only stretch on the vertical axis when torqued, eliminating the twisting forces that occur with conventional head bolts. This results in superior head gasket sealing and reliability, making this kit essential for racing applications, engine rebuilds, and high-boost turbocharged setups. Each kit includes detailed installation instructions and ARP's premium assembly lubricant.
