Overview:

The Eagle Forged 4340 Steel H-Beam Connecting Rods are precision-engineered performance components designed to upgrade and reinforce the bottom end of your HEMI engine. Crafted for serious enthusiasts and professional builders, these rods are ideal for Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L, 6.4L, and 6.2L HEMI engines, including high-output variants like the SRT8, Hellcat, and Trackhawk.

Built to withstand high horsepower and RPM demands, these connecting rods provide exceptional strength and durability, making them perfect for street performance, track use, and forced induction applications. Whether you are building a stroker engine or upgrading for increased reliability, Eagle’s rods deliver consistent, reliable performance under extreme conditions.

Key Features:

These connecting rods incorporate advanced design and materials to ensure maximum strength and longevity:

• Constructed from forged 4340 steel for superior tensile strength and fatigue resistance
• H-beam design optimizes strength-to-weight ratio for enhanced durability and reduced flex
• Floating wrist pin style for smooth articulation and reduced wear
• Cap screw retention with ARP 8740 chromoly steel bolts rated at 180,000 psi tensile strength
• Shot-peened and magnafluxed for crack detection and improved fatigue life
• Weight-matched set for balanced engine operation and reduced vibration
• Clearanced for stroker crankshaft compatibility
• 12-point bolt head style for secure and precise fastening
• Big end bore diameter of 2.1250 inches and rod journal diameter of 2.000 inches
• Capable of handling up to 750 horsepower and 7,500 RPM

Construction & Design:

Each connecting rod is forged from premium 4340 steel, a material known for its exceptional strength and toughness under high stress. The H-beam configuration provides an optimal balance between rigidity and weight, reducing the risk of rod failure during high-performance operation. The rods are meticulously shot-peened to relieve surface stresses and magnafluxed to ensure structural integrity, guaranteeing reliability in demanding environments.

The floating wrist pin design allows for smooth articulation between the piston and rod, minimizing friction and wear. ARP 8740 chromoly steel bolts secure the caps with a 12-point head design, delivering consistent clamping force and resistance to stretching or loosening under extreme loads.

Installation & Fitment:

These connecting rods are designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram HEMI engines, including 5.7L, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat and Trackhawk models. Installation requires standard engine assembly procedures, but note that some engine blocks may require clearancing to accommodate the rods, especially in stroker applications. Professional installation is recommended to ensure proper torque specifications and alignment.

What's Included:

• Set of 8 forged 4340 steel H-beam connecting rods
• ARP 8740 chromoly steel cap screws (7/16 inch diameter)
• Floating wrist pins
• Installation instructions and technical specifications

Ideal For:

This set is perfect for performance enthusiasts, engine builders, and racers looking to upgrade the bottom end of their HEMI-powered vehicles. Whether building a naturally aspirated stroker, forced induction setup, or a high-RPM race engine, these connecting rods provide the strength and reliability needed to handle increased power and stress.

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.
