BBC 4340 H-Beam Rods 6.800 4th-Gen

The EAGLE BBC 4340 H-Beam Rods 6.800 4th-Generation (Part No. CRS68004D) are forged connecting rods engineered for big block Chevy engine builds demanding superior strength and reliability. Designed with H-beam geometry, these rods deliver the structural integrity required for high-performance and heavy-duty applications where precision and durability are non-negotiable.

Each rod measures 6.800 inches in length and features 7/16-inch cap screws secured with ARP2000 bolts—premium fasteners rated for demanding engine environments. The bushed design allows for precise wrist pin clearance, while the forged steel construction provides the fatigue resistance required under sustained high-load conditions. This set of eight rods is suitable for complete engine rebuilds or high-performance modifications where OEM or equivalent strength specifications are mandatory.

EAGLE rods are recognized in the engine building and performance community for consistent metallurgy and tight tolerances. The H-beam profile reduces deflection during combustion events, protecting against rod flex that can compromise long-term engine stability. Builders working on marine, automotive, or industrial big block applications choose these rods for their proven track record across thousands of engine builds.

Whether rebuilding a classic big block for reliability or constructing a high-output engine combination, these EAGLE connecting rods provide the structural foundation needed to handle extended service. Weighing 15.55 lbs for the complete eight-piece set, they integrate easily into standard BBC engine configurations and are compatible with both stock and modified piston assemblies.
