This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering clamp loads in the 230,000-260,000 PSI range. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels ­ L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.

Applies to:

  • Chevrolet Small Block


Engine Pro H-Beam Connecting Rods are forged from 4340 steel. All of our rods are magnafluxed, heat treated, stress relieved, shot peened, and sonic tested to ensure they provide the strength required for high horsepower applications. All rods are produced on CNC machinery and are finished in the USA to ensure precise big end and pin end bore sizes. We weight match all of our sets of rods to + or -1.5 grams to make balancing easier. Silicon bronze bushings are installed for use with floating pins. Bolt lube and torque specifications are included. Engine Pro rods equipped with ARP's standard 8740 bolt are rated for up to 700 horsepower in small blocks, and 850 horsepower in big block applications.
