Construction & Design

Carrillo Pro-H connecting rods are forged from high-strength steel alloys using a proprietary forging process that ensures a uniform grain structure and superior mechanical properties. This manufacturing method results in rods that offer exceptional strength and resistance to fatigue, critical for high-performance and heavy-duty engines.

The rods feature a wide male collar bolt design that increases the bolt shear area and clamping force, significantly reducing the risk of bolt stretch or failure under extreme loads. Each rod is CNC-machined to tight tolerances, guaranteeing consistent weight and perfect alignment for smooth engine operation. The 6.125-inch length is carefully optimized to match the HEMI engine’s stroke and bore dimensions, maintaining proper piston positioning and minimizing stress on the crankshaft and bearings.

Installation & Fitment

This connecting rod set is a direct-fit replacement for factory rods in the specified Dodge, Chrysler, Jeep, and Ram models equipped with 5.7L or 6.1L HEMI engines. Installation requires standard engine disassembly and reassembly procedures, including proper torqueing of the WMC bolts to manufacturer specifications. No modifications to the engine block or crankshaft are necessary, making these rods an excellent upgrade for rebuilds or performance builds.

Professional installation is recommended to ensure correct clearances and optimal engine performance.
