CP-Carrillo PS737130H 7.3L Powerstroke Pro-H Connecting Rods With H-11 Bolts

Proprietary Carrilloy SteelCP-Carrillo uses a proprietary steel to manufacture its connecting rods, named Carrilloy. It is a chrome, nickel, moly, vanadium alloy which meets all VAR (vacuum arc re-melt ASTM standards). The heat is validated by the supplier and an independent metallurgist that confirmed the desired physical and chemical properties of steel. The heat treatment is conducted via a mar-aged operation, resulting in UTS of 195,000 with a yield of 182,000 while maintaining the critical elements of low notch-sensitivity and ductility. 

Precision Manufacturing ProcessConnecting rods from CP-Carrillo are crafted from an oversized forging resulting in the proper grainflow as well as the surface removal of any potential inclusions or surface conversions generated by the forging process. Every CNC machine at CP-Carrillo is equipped with probing to accurately validate dimensional integrity. Each part is magnafluxed at least twice during the production process. Each piece is Rockwell tested to validate the heat treat procedure. A final shot peen operation completes the part. 

H11 BoltsIncluded with these connecting rods are WMC-H7 (H11) bolts. The H-11 Bolts feature an Ultimate Tensile Strength (UTS) of 220KSI and are good for about 15-18 torque cycles. These high strength connecting rod fasteners are designed for secure, repeatable clamping capable of handling elevated performance conditions. All bolts feature asymmetrical threads, where each thread is slightly different from the previous one, providing evenly distributed thread engagement. This design enhances clamp load and extends the fastener's fatigue life. For added durability, a Mahle steel bushing is included, with Cap Relief to assist in oil evacuation for engines running at higher loads and RPM's.
