Overview:

The Eagle 4340 H-Beam Connecting Rods are precision-engineered components designed to enhance the durability and performance of Chrysler 6.4L HEMI engines. Crafted for serious enthusiasts and professional racers, these rods provide the strength and reliability needed to withstand the rigors of high-performance and competition use. Sold as a complete set of eight, they ensure balanced operation and optimal engine efficiency.

These connecting rods are ideal for those upgrading their engine internals to handle increased power output, offering peace of mind through superior construction and exacting manufacturing standards.

Key Features:

Built to meet the demands of high-performance Chrysler engines, the Eagle 4340 H-Beam Connecting Rods include the following key features:

• Manufactured from forged 4340 steel for exceptional strength and fatigue resistance
• H-Beam design for an optimal balance of weight and rigidity
• Two-piece forging process ensuring superior structural integrity
• Fully machined and shot-peened surfaces to enhance durability and reduce stress risers
• Precision sizing held to exact tolerances for consistent fitment and performance
• Weight-matched set of eight rods for balanced engine operation
• Designed specifically for Chrysler 6.4L HEMI engines with a .945" wrist pin diameter
• Recommended torque specification of 63 ft-lbs using ARP moly lube for proper installation
• Ideal for competition and high-performance applications

Construction & Design:

Each connecting rod is forged from premium 4340 steel, a material known for its high tensile strength and toughness, making it well-suited for the extreme conditions of racing and high-output engines. The H-Beam configuration provides a robust yet lightweight structure that resists bending and twisting forces during high RPM operation.

The rods undergo a two-piece forging process, which enhances grain flow and structural integrity. After forging, they are fully machined to precise dimensions and shot-peened to relieve surface stresses, increasing fatigue life and reliability under demanding conditions.

Installation & Fitment:

The Eagle 4340 H-Beam Connecting Rods are designed as direct replacements for Chrysler 6.4L HEMI engines featuring a .945" wrist pin. Installation requires standard engine assembly procedures, with careful attention to torque specifications. It is critical to torque the rod bolts to 63 ft-lbs using ARP moly lube to ensure proper clamping force and longevity.

These rods are sold as a weight-matched set of eight, simplifying balancing and assembly. No modifications are typically necessary when installing on compatible Chrysler engines, making them a straightforward upgrade for performance builds.

What's Included:

• Set of 8 Eagle 4340 forged H-Beam connecting rods
• Weight-matched for balanced engine performance

Ideal For:

This set of Eagle 4340 H-Beam Connecting Rods is ideal for automotive enthusiasts, professional racers, and engine builders seeking durable, high-strength components for Chrysler 6.4L HEMI engines.
