Callies Ultra Enforcer I-Beam connecting rods are built specifically for high torque, high boost applications in the Ford 4.6L Modular and 5.0L Coyote engine family. Each rod in this eight-piece set is forged from proprietary 4330V TimkenSteel product formulated to Callies' exact specifications, then manufactured entirely at their Fostoria, Ohio facility. The result is a connecting rod with documented material traceability and consistent dimensional quality from the first set to the hundredth.
Engineered for boosted power. Fortified tower flanges and a buckle-resistant I-Beam profile give these rods enhanced resistance to bending and twisting under the cylinder pressures generated by turbocharged and supercharged engines. Pressure angle arches at the pin end guarantee wrist pin stability, and the increased mass throughout the beam supports up to 250 horsepower per cylinder.
Dimensional repeatability that protects your build. Big-end bore roundness is maintained through an extended stress-relief process and multiple re-torque cycles during manufacturing. This burnishes threads and bolt seat faces so the bores stay round through repeated disassembly and reassembly, a critical concern for any engine builder who plans to inspect or service the short block.
Hardware included, no upgrades required. L-19 bolts come standard, delivering high tensile strength and consistent clamping force at the rod-to-cap joint. The pin bushings arrive chamfered and honed to proper high-performance oil clearance, parting line edges are generously chamfered to ease bearing shell installation, and bearing tab slots are de-burred for full tab seating right out of the box.
Specifications at a glance. Each rod measures 5.933 inches (151 mm) center-to-center, targets a 2.239-inch (57 mm) rod journal, accepts a 0.866-inch (22 mm) wrist pin, and weighs 706 grams. The forged 4330V steel construction delivers a high strength-to-weight ratio appropriate for heavily boosted street and race applications.
