Callies Ultra Enforcer I-Beam connecting rods bring serious material science and precision manufacturing to the 3.5L EcoBoost found in the 2011-2026 F-150. Produced from 4330V TimkenSteel forged in Trenton, Michigan and machined entirely at Callies' Fostoria, Ohio facility, each rod in this six-piece set traces a complete manufacturing history maintained by the production team. The result is a component built for boosted applications where cylinder pressure, heat, and stress cycles exceed what factory rods can reliably handle.
Buckle-resistant I-Beam architecture. The I-Beam profile resists the bend and twist loads generated by forced induction, while fortified tower flanges add structural mass exactly where turbo and supercharged engines demand it. Pressure angle arches at the pin end lock the wrist pin in position under extreme cylinder pressure, preventing micro-movement that accelerates wear and shortens component life.
Rated to handle up to 250 horsepower per cylinder. Each rod is engineered to withstand the cylinder loads that accompany serious boost builds. Whether the 3.5L EcoBoost is being built for towing-focused reliability or maximum output, the Ultra Enforcer platform provides margin beyond the rated threshold to keep the bottom end intact across a wide range of build strategies.
Dimensional repeatability you can count on. Big end bore roundness holds through repeated disassembly and reassembly cycles thanks to an extended stress relief process and multiple re-torque passes during manufacturing. Residual machining stresses are released before the rods leave the facility, so the bores stay in spec whether they are being torqued for the first time or reinstalled after an inspection.
Bolt options matched to the build. Standard L-19 bolts are included. For applications pushing beyond standard parameters, Callies offers MP 3.5 bolts or Custom Age 625 bolts as selectable upgrades.
