About ARP2000 Material:

ARP2000 is an advanced alloy steel that can be safely heat-treated to higher levels than standard chrome moly, producing greater strength and reliability. This material is widely used in short track and drag racing applications as an upgrade from 8740 chrome moly in both steel and aluminum applications. When properly installed, ARP2000 fasteners resist stress corrosion and hydrogen embrittlement while delivering consistent, repeatable clamping force.

Complete kit includes all necessary fasteners for a professional installation. ARP fasteners are the preferred choice of engine builders and racers worldwide who demand the ultimate in strength, precision, and reliability.
