Designed specifically for Ford Modular engines, these Ultra I-Beam connecting rods accommodate the unique rod journal diameters and widths of Modular blocks with precision-machined .866” wrist pin bores for a perfect fit. Proudly made in the USA, each rod is forged from high-strength Timken 4330V steel in Michigan and fully machined at Ultra’s Fostoria, Ohio facility, ensuring top-tier quality and consistency.
Engineered for extreme duty and high-RPM applications, the rods incorporate advanced geometric design features that optimize strength while resisting the intense loads and stresses experienced during racing. The use of AMS 642 bronze alloy bushings within the wrist pin housing eliminates deformation and extrusion, extending durability under severe conditions.
Each rod is secured with high-alloy ARP cap screws, manufactured with rolled threads to provide superior thread engagement and a consistent clamping load—critical for maintaining integrity at elevated RPM and power levels.
