Product Description

The ARP 201-4602 Head Stud Kit is engineered for BMW M30 3.0L and 3.4L inline-six engines, commonly found in the 1977-1993 BMW 530i, 535i, 635CSi, and 735i models. Upgrading to ARP's high-performance head studs ensures consistent clamping force and improved cylinder head alignment, which is crucial for high-revving or turbocharged applications.

Manufactured from 8740 chromoly steel and heat-treated to 200,000 psi tensile strength, these studs offer superior durability and resistance to stretching under extreme conditions. The undercut design of the studs helps equalize the stretch across all studs, providing uniform clamping force and reducing the risk of head gasket failure.

The kit includes 12 studs, nuts, hardened washers, and ARP assembly lubricant, providing everything needed for a complete installation. Whether you're building a street performance engine or preparing for track use, the ARP 201-4602 Head Stud Kit delivers the reliability and strength required for optimal engine performance.
