Eagle CRS6243H3D Forged 4340 H-Beam Connecting Rods for 2003-24 Chrysler/Dodge

Vehicle Fitment

• 2003-2024 Chrysler / Dodge / Jeep Gen III 5.7L HEMI V8 (Ram, Charger, Challenger, 300, Durango, SRT etc.)
• 2005-2010 Chrysler / Dodge / Jeep 6.1L HEMI V8 (SRT-8 trim and equivalent performance models)

Fitment Notes

• Does *not* fit Gen I or Gen II HEMI engines (pre-2003)
• Does *not* fit 6.4L, Hellcat, Demon, or other performance HEMI variants using different rod or pin specs unless modifications are made
• Uses .927-inch floating wrist pin; block/wrist pin must match
• Drivetrain type (FWD/RWD/AWD/4WD) generally irrelevant for internal engine component - fits across drivetrain variants of the listed models

Features

• Forged 4340 steel H-Beam construction for high strength and fatigue resistance
• Bushed for full-floating wrist pins with silicon bronze bushings for smooth operation and durability
• Shot-peened, magnafluxed, x-rayed and sonic tested for structural integrity under high stress
• Precision cap alignment sleeves to ensure accurate rod cap fit and maintain alignment during load
• Weight-matched set (8 rods) to minimize imbalance and vibration
• Uses 7/16-inch ARP 8740 bolts (standard); upgrade options available for higher HP builds
• Tight machining tolerances on bore, width, and journal dimensions for consistent performance
• Typical rod journal design allows direct replacement of stock rods with these without crank or block modifications (when specs align)

Specifications

• Center-to-center rod length: **6.243 in** (~158.57 mm) 
• Wrist pin diameter (pin size): **0.927 in** (~23.56 mm) floating pin 
• Rod journal diameter (big end): **2.126 in** (~54.0 mm) 
• Big-end width: **0.932 in** (~23.68 mm) 
• Pin-end width: **0.932 in** (~23.68 mm) 
• Weight per rod: approximately **640 g**; set of 8 rods weight matched
• Bolt specification: **7/16-inch ARP 8740** (standard), upgradeable to ARP 2000 or L-19 for higher strength builds 
• Torque spec: ~**63 ft-lbs** using ARP moly lube only on bolt threads/nut surfaces 

Included Components

• 8x Eagle CRS6243H3D forged 4340 H-Beam connecting rods
• 8x standard 7/16-inch ARP 8740 rod cap bolts
• 1x set of rod bolt lubrication and torque specification instructions

Product Description

The Eagle CRS6243H3D rods are high-performance, heavy-duty connecting rods designed for Gen III HEMI V8 engines, specifically the 5.7L (2003-2024) and 6.1L (2005-2010) variants. Constructed from forged 4340 steel and built in an H-Beam configuration, they offer improved strength, stiffness, and durability over stock rods. Floating wrist pins, precision machining, and multiple quality control processes (magnaflux, sonic test, x-ray) ensure these rods can handle high loads - ideal for boosted, high RPM, or heavily stressed builds.

This rod set is especially suited to enthusiast builds seeking reliability without going into extreme / exotic HEMI variants. Fitment is confirmed through 2024 for the 5.7L models. **Fitment in 2025** for the 6.1L is unconfirmed since OEM use of that engine ended in 2010. No trimming of engine components or major internal modifications are required if your engine uses the matching .927-inch floating pin specification. Always double check wrist pin type (floating vs fixed), pin diameter, and ensure your torque strategy matches that required for the ARP bolts to enjoy full performance and longevity from these rods.
