• Constructed from forged 4340 steel for maximum strength and fatigue resistance
• H-beam design optimizes strength-to-weight ratio for enhanced durability
• Center-to-center length of 6.243 inches, tailored for factory and stroker engine builds
• Floating wrist pin style with a pin end bore diameter of 0.927 inches
• Big end bore diameter of 2.2520 inches with a rod journal diameter of 2.126 inches
• Shot-peened finish to improve fatigue life and surface durability
• Magnafluxed for crack detection, ensuring structural integrity
• Weight-matched set with an approximate rod weight of 640 grams each for balanced engine operation
• Cap screw retention with ARP L19 alloy bolts rated at 260,000 psi tensile strength for secure fastening
• 12-point bolt head style for precise torque application and reliability

Construction & Design:

Each connecting rod is forged from premium 4340 chromoly steel, a material renowned for its toughness and fatigue resistance under high-stress conditions. The H-beam configuration provides an optimal balance of strength and weight, reducing reciprocating mass without compromising durability. Eagle’s meticulous manufacturing process includes shot-peening to enhance surface hardness and fatigue life, as well as magnaflux inspection to detect any microscopic cracks before assembly.

The rods feature precision-machined big and small end bores to ensure tight tolerances and smooth bearing fitment. ARP L19 alloy bolts secure the caps with exceptional clamping force, critical for high-performance and forced induction applications. This combination of materials and engineering ensures these rods can handle the demands of both naturally aspirated and boosted engines.

Installation & Fitment:

These connecting rods are designed as direct replacements for Chrysler, Dodge, Jeep, and Ram engines equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. Installation requires standard engine assembly procedures and is best performed by experienced technicians or engine builders. No modifications are necessary for stock or stroked engines within the specified bore and journal dimensions.

Eagle recommends pairing these rods with Clevite CB1808A or King CR8032SM rod bearings for optimal performance and durability. Proper torque specifications and assembly techniques should be followed to ensure reliable operation.

What's Included:

• Set of 8 forged 4340 steel H-beam connecting rods
• ARP L19 7/16-inch diameter connecting rod bolts with 12-point heads
• Cap screws for secure retention
• Shot-peened and magnafluxed rods, weight-matched for balanced engine assembly

Ideal For:

This connecting rod set is ideal for performance enthusiasts, professional engine builders, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram Hemi engines. Whether building a naturally aspirated powerhouse or a forced induction monster, these rods provide the strength and reliability needed to support increased power levels and high RPM operation. They are well-suited for street performance, drag racing, road racing, and off-road applications where durability and precision are paramount.

Eagle Specialty Products manufactures high-strength engine components—most notably connecting rods and crankshafts—intended for performance and racing engines. These rotating-assembly upgrades are commonly used in builds that demand higher strength margins for boost, nitrous, sustained RPM, or competition use.
