Callies Ford 2.3L EcoBoost Ultra Enforcer I-Beam Connecting Rod 4pc Set

Callies Ultra Enforcer I-Beam connecting rods bring purpose-built boosted-engine engineering to the 2.3L EcoBoost found in the 2015-2026 Mustang EcoBoost and Focus RS. Produced from clean 4330V TimkenSteel material formulated to Callies' exact specifications, each rod is forged in Trenton, Michigan and fully manufactured at Callies' Fostoria, Ohio facility. Every step of the production history is tracked by the manufacturing team, so the material and workmanship behind each rod are fully documented and verifiable.

Built specifically for boosted applications. The I-Beam profile uses a buckle-resistant cross-section with increased mass and pressure-angle arches that lock the wrist pin in place under the cyclical loads generated by turbocharged and supercharged engines. Robust tower flanges resist both bending and twisting forces, and the design is rated to support up to 250 horsepower per cylinder, making these rods appropriate for serious power builds on the 2.3L platform.

Dimensional repeatability through rigorous processing. Big-end bore roundness is maintained through an extended stress-relief process combined with multiple re-torque cycles. Residual machining stresses are released and thread surfaces are burnished so the bore stays round through repeated assembly and disassembly cycles, eliminating the dimensional drift that affects many aftermarket connecting rods after their first rebuild.

Prep work completed at the factory. Pin bushings arrive chamfered and honed to proper high-performance oil clearance. Parting-line edges are generously chamfered to prevent bearing-shell scraping during installation, and bearing-locating tab slots are deburred so each tab seats fully on the first assembly. These details reduce preparation time on the engine stand and lower the risk of installation errors.

Bolt options matched to the build. Standard rods ship with L-19 bolts for proven tensile strength and clamping force. Builders requiring additional strength can select the MP 3.5 or Custom Age 625 bolt upgrades, so the rod set arrives ready for the intended power level without sourcing hardware separately.
