About 8740 Chrome Moly Material:

8740 chrome moly is a quench and temper steel that offers excellent toughness and adequate fatigue properties for most racing applications. When properly manufactured with rolled threads after heat-treatment—as is standard ARP practice—this material delivers reliable performance at a cost-effective price point for street performance, road racing, and many drag racing applications.

Installation Note: Always follow ARP's installation instructions and use the recommended lubricant to achieve proper clamping force and fastener life.
