CRS6243H3D

Overview:

The Eagle Forged Steel Connecting Rods are precision-engineered components designed for high-performance applications, specifically tailored for Chrysler 6.4L HEMI engines. Crafted from premium 4340 forged steel, these H-beam rods provide exceptional strength and durability, making them ideal for competition and serious enthusiasts seeking reliable engine internals. Sold as a complete set of eight, each rod is weight-matched to ensure balanced engine operation and reduce vibration, contributing to improved engine longevity and performance.

These connecting rods are perfect for builders looking to upgrade their engine’s bottom end with components that can withstand increased power and RPM levels. Whether you are rebuilding a street performance engine or assembling a race-ready powerplant, Eagle’s forged rods offer the toughness and precision needed for demanding conditions.

Key Features:

Engineered for strength and precision, these connecting rods incorporate advanced manufacturing techniques and materials to deliver superior performance:

• Constructed from high-grade 4340 forged steel for maximum tensile strength and fatigue resistance
• H-beam design optimizes strength-to-weight ratio, enhancing durability without unnecessary mass
• Manufactured from a two-piece forging process to ensure structural integrity
• Fully machined and shot-peened surfaces improve fatigue life and reduce stress concentrations
• Precision sizing held to exact tolerances for consistent fit and performance
• Weight-matched set of eight rods for balanced engine dynamics and smooth operation
• Compatible with Chrysler 6.4L HEMI engines using a .927" wrist pin diameter
• Recommended torque specification of 63 ft-lbs using ARP moly lube for fastener longevity
• Ideal for competition use where reliability under high stress is critical

Construction & Design:

The Eagle connecting rods are forged from premium 4340 steel, a material known for its excellent strength and toughness under extreme conditions. The rods feature an H-beam cross-section, which provides a superior strength-to-weight ratio compared to traditional I-beam designs. This geometry helps resist bending and twisting forces encountered during high-RPM operation.

Each rod undergoes a two-piece forging process, ensuring a dense, uniform grain structure that enhances durability. After forging, the rods are fully machined to precise dimensions and shot-peened to introduce beneficial surface compressive stresses, significantly improving fatigue resistance. This meticulous manufacturing process results in a connecting rod set that meets the stringent demands of high-performance and racing engines.

Installation & Fitment:

These connecting rods are designed as direct replacements for Chrysler 6.4L HEMI engines with a .927" wrist pin size. Installation requires standard engine assembly procedures, including proper torque application of the rod bolts to 63 ft-lbs using ARP moly lube to ensure optimal fastener performance and longevity. No additional modifications are typically necessary when upgrading from OEM rods, making them a straightforward choice for engine builders.

What's Included:

• Set of 8 Eagle forged 4340 steel H-beam connecting rods
