BBC FSI 4340 I-Beam Rod Set 6135

The EAGLE BBC FSI 4340 I-Beam Rod Set 6135 is a precision forged connecting rod assembly engineered for big block Chevrolet engine builds. This 6.135-inch I-beam rod features a bushed design with 7/16-inch cap screws and an 8740 bolt specification, delivering the structural integrity and load-bearing capacity required for high-performance and heavy-duty automotive applications. Whether rebuilding a classic muscle car engine, constructing a street performance build, or restoring vintage big block Chevy power, this rod set provides the verified engineering needed for dependable operation.

The forged steel construction and I-beam geometry distribute loads efficiently across the rod length, minimizing flex under dynamic stress. The bushed design accommodates the wrist pin with precision fit, while the 8740 bolt specification ensures fastener reliability under peak combustion pressures. At 14.5 pounds per unit, this rod balances structural mass appropriately for reliable reciprocating motion in big block displacement ranges. The 9.6 x 4.2 x 10.8-inch envelope confirms this is a full-size connecting rod assembly for large-displacement Chevy engines, not compact variants.

Buyers performing engine block work, crate engine assembly, or complete bottom-end rebuilds rely on verified OEM-specification connecting rods to maintain factory reliability and performance boundaries. This EAGLE rod set is sold individually per unit—verify your complete set quantity before checkout. Proper rod bearing clearance, bolt torque specification, and piston pin fit should be confirmed against your engine manual during assembly. Pairing verified connecting rods with quality bearings, fasteners, and machine work ensures long service life in both street and performance applications.
