What material are these bolts made from?

These bolts are constructed from ARP 625+ alloy. This material is known for its exceptional strength and resistance to stretching under high heat and pressure, making it suitable for demanding engine applications.

What is the primary advantage of using ARP 625+ bolts?

The main advantage is their increased tensile strength and fatigue resistance compared to standard fasteners. This provides a more robust clamping force and helps ensure components remain securely fastened under significant stress in high-performance engines.

Are these bolts sold individually or as a set?

This product is sold as a set of four Manley 3/8 ARP 625+ bolts.

Product Details

This set includes four Manley 3/8 ARP 625+ bolts. These are well-built fasteners designed for demanding engine applications where superior clamping force and reliability are essential. ARP 625+ material is known for its exceptional strength and fatigue resistance, making these bolts a solid choice for high-performance engine builds.

The ARP 625+ alloy offers a notable increase in tensile strength compared to standard ARP 2000 bolts, providing a more robust clamping solution. This material is also more resistant to stretching under extreme heat and pressure, which is critical for maintaining seal integrity in high-output engines. Using these bolts helps ensure that critical engine components stay securely fastened, even under significant stress.

When rebuilding or modifying an engine, using fasteners that can handle the increased loads is crucial. These Manley bolts, made with ARP 625+ material, are a popular option for builders who want added confidence in their engine's internal components.
