CRS6243H3D

Overview:

The Eagle Forged 4340 Steel H-Beam Connecting Rods are precision-engineered performance components designed to upgrade the bottom end of Chrysler, Dodge, Jeep, and Ram engines, specifically the 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk powerplants. Crafted for enthusiasts and professional builders seeking enhanced strength and durability, these rods provide a reliable foundation for high-horsepower builds up to 800 hp. They are ideal for street performance, racing, and forced induction applications where factory rods may fall short under extreme stress.

Each set includes eight rods, perfectly weight-matched to ensure smooth engine operation and balanced reciprocating mass. The H-beam design offers an excellent strength-to-weight ratio, making these rods a popular choice for high-performance builds that demand both durability and responsiveness.

Key Features:

These connecting rods incorporate advanced materials and manufacturing techniques to deliver superior performance and reliability:

• Constructed from forged 4340 steel for exceptional tensile strength and fatigue resistance
• H-beam beam style optimizes strength while minimizing weight
• Floating wrist pin design for reduced friction and improved durability
• End bore diameter of 0.927 inches and rod journal diameter of 2.126 inches for precise fitment
• Cap retention via high-strength ARP 8740 chromoly steel cap screws with 180,000 psi tensile strength
• Shot-peened finish enhances fatigue life by relieving surface stresses
• Magnafluxed to detect internal flaws and ensure structural integrity
• Weight-matched set with an approximate rod weight of 640 grams each for balanced engine dynamics
• Big end width of 0.932 inches and pin end width of 0.932 inches for compatibility with factory clearances
• Designed for direct fitment with no stroker clearance modifications required

Construction & Design:

These connecting rods are forged from premium 4340 chromoly steel, a material renowned for its high tensile strength and toughness under extreme conditions. The H-beam design provides a robust cross-section that resists bending and twisting forces encountered during high-RPM operation. Each rod undergoes shot peening, a process that introduces compressive surface stresses to improve fatigue resistance and longevity.

Additionally, the rods are magnafluxed to detect any microscopic cracks or imperfections, ensuring only flawless components are installed in your engine. 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 under high loads.

Installation & Fitment:

These Eagle connecting rods are engineered for direct bolt-in installation on 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 necessary, simplifying the upgrade process. Professional installation is recommended to ensure proper torque specifications and bearing clearances are achieved for optimal performance and reliability.

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

Ideal For:

This set is perfect for performance enthusiasts, engine builders, and racers upgrading their Chrysler, Dodge, Jeep, or Ram Hemi engines for increased horsepower and durability. Whether building a naturally aspirated powerhouse, a forced induction monster, or a track-focused machine, these rods provide the strength and reliability needed to handle power levels up to 800 hp without compromise.

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.
