Construction & Design:
Carrillo’s Straight Pro-H connecting rods are forged from premium 4340 chromoly steel, a material known for its excellent tensile strength and toughness. The rods undergo a rigorous heat treatment process to maximize fatigue life and resistance to stress fractures. The 3/8" WMC bolts are engineered to provide superior clamping force, ensuring the rod caps remain securely fastened under extreme engine loads.
The straight design of these rods aligns perfectly with the Hemi engine’s architecture, reducing side loading and wear on the cylinder walls. Precision CNC machining guarantees tight tolerances and balanced rod weights, which contribute to smoother engine operation and improved reliability at high RPMs.
Installation & Fitment:
These connecting rods are designed as direct replacements for factory rods in compatible Chrysler and Dodge Hemi engines. Installation requires standard engine disassembly and reassembly procedures, typically performed by experienced mechanics or engine builders. No modifications to the engine block or pistons are generally necessary, making them a straightforward upgrade for performance builds.
Fitment covers a wide range of vehicles equipped with 5.7L and 6.1L Hemi engines, including Dodge Ram 1500, 2500, 3500 (various years), Dodge Durango, Chrysler 300, Dodge Magnum, Jeep Grand Cherokee, Dodge Charger, Jeep Commander, and Dodge Challenger models from 2003 through 2025, depending on the specific vehicle.
