Overview:

The Eagle Forged 4340 Steel H-Beam Connecting Rods are precision-engineered components designed to upgrade and reinforce the bottom end of your Chrysler, Dodge, Jeep, or Ram Hemi engine. These rods are ideal for enthusiasts and professional builders seeking enhanced strength and durability for high-performance applications, including naturally aspirated and forced induction setups. Crafted to exacting standards, they provide reliable performance under extreme conditions, making them a trusted choice for 5.7L to 6.4L Hemi engines.

Whether you are rebuilding your engine for increased power or replacing worn factory rods, these Eagle rods deliver the toughness and consistency needed to handle elevated horsepower and torque levels while maintaining engine balance and reliability.

Key Features:

Engineered for strength, precision, and durability, these connecting rods offer the following key features:

• Constructed from forged 4340 steel for superior tensile strength and fatigue resistance
• H-beam design optimizes strength-to-weight ratio for enhanced durability without excessive weight
• Shot-peened and magnafluxed for improved fatigue life and crack detection
• Floating wrist pin style with a 0.927-inch end bore diameter for smooth articulation
• Cap screw retention using ARP L19 alloy bolts with 260,000 psi tensile strength for secure fastening
• Weight-matched sets to ensure engine balance and smooth operation
• Compatible with Clevite CB1808A or King CR8032SM rod bearings as recommended by Eagle
• Clearance and dimensions optimized for stock stroke applications (not clearanced for stroker kits)
• Precision-machined big end bore diameter of 2.2520 inches and rod journal diameter of 2.126 inches

Construction & Design:

Each connecting rod is forged from premium 4340 steel, a high-strength alloy known for its toughness and resistance to wear and fatigue. The H-beam design provides an ideal balance between rigidity and weight savings, reducing the risk of rod flex or failure under high loads. Eagle’s manufacturing process includes shot-peening to induce beneficial compressive stresses on the surface and magnaflux inspection to detect any microscopic cracks, ensuring every rod meets stringent quality standards.

The rods feature floating wrist pins and are secured with ARP L19 alloy bolts, renowned for their exceptional tensile strength and reliability in demanding performance environments. The precision machining and weight matching of each rod set contribute to consistent engine balance and smooth operation at high RPMs.

Installation & Fitment:

These connecting rods are designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram engines equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat or Trackhawk powerplants. Installation requires standard engine assembly procedures and is best performed by experienced mechanics or engine builders. No modifications are necessary for stock stroke engines, but compatibility with stroker kits is not supported due to lack of clearance machining.

Sold individually, these rods allow for flexible replacement or custom engine builds. Eagle recommends pairing them with specified rod bearings for optimal performance and longevity.

What's Included:

• One forged 4340 steel H-beam connecting rod
• ARP L19 alloy cap screws (7/16-inch diameter, 12-point head)
• Proof of mechanical and electrical failure coverage plan

Ideal For:

These connecting rods are ideal for performance enthusiasts, engine builders, and racers who demand enhanced bottom-end strength for Chrysler and Dodge Hemi engines. They are well-suited for naturally aspirated builds, forced induction setups, and street or track applications where reliability and durability under high stress are critical. Whether upgrading a stock engine or assembling a high-performance build, Eagle’s forged rods provide the confidence and quality needed to support increased power levels.

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.
