Key Features:

Engineered for strength, precision, and reliability, the Eagle H-beam rods offer the following key features:

• Constructed from forged 4340 steel for superior tensile strength and fatigue resistance
• H-beam design optimizes weight-to-strength ratio, reducing reciprocating mass while maintaining durability
• Center-to-center length of 6.243 inches ensures proper fitment and stroke compatibility
• Floating wrist pin design with a 0.984-inch end bore diameter for smooth articulation
• Big end bore diameter of 2.2520 inches and rod journal diameter of 2.126 inches for precise crankshaft fit
• Shot-peened finish enhances fatigue life by relieving surface stresses
• Cap screw retention with ARP 7/16-inch diameter bolts made from 8740 chromoly steel, rated at 180,000 psi tensile strength
• Weight-matched set with an approximate rod weight of 640 grams each for balanced engine operation
• Compatible with recommended bearings such as Clevite CB1808A or King CR8032SM
• Torque specifications: 63 ft-lbs using ARP moly lube for optimal bolt stretch and clamping force

Construction & Design:

These connecting rods are forged from premium 4340 chromoly steel, a material renowned for its high tensile strength and toughness. The forging process ensures a dense grain structure, which significantly improves fatigue resistance and durability under high-stress conditions. The H-beam configuration provides an excellent balance between rigidity and weight savings, allowing the rods to withstand the rigors of high RPM and boost pressures without unnecessary mass.

Each rod is precision-machined to exact tolerances, including the big end and pin end bores, ensuring a perfect fit on the crankshaft and piston pins. The rods are shot-peened to enhance surface hardness and reduce the risk of crack initiation, extending the service life of the components. The use of ARP 8740 chromoly steel bolts with a 12-point head design guarantees secure cap retention and consistent clamping force, critical for maintaining rod integrity during engine operation.

Installation & Fitment:

This set of eight connecting rods is designed as a direct fit for Chrysler, Dodge, Jeep, and Ram engines equipped with the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. No modifications or clearancing for stroker kits are required, simplifying installation. Proper torque application using ARP moly lube to 63 ft-lbs is essential to ensure bolt stretch and rod cap retention.

Recommended bearings include Clevite CB1808A or King CR8032SM to maintain optimal clearance and durability. Professional installation is advised to confirm correct rod bearing clearances and overall engine assembly integrity.

What's Included:

• Set of 8 Eagle Forged 4340 Steel H-Beam Connecting Rods
• ARP 7/16-inch 8740 chromoly steel cap screws (pre-installed)
• Installation guidelines and torque specifications

Ideal For:

These connecting rods are ideal for performance enthusiasts, engine builders, and racers upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram Hemi engines. They are perfectly suited for naturally aspirated builds, supercharged, or turbocharged applications where increased strength and reliability are paramount. Whether upgrading a street car, drag racer, or off-road machine, these rods provide the durability and precision needed for high-output engines.

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.
