• Balanced for smooth engine operation and reduced vibration

Construction & Design:

Carrillo connecting rods are manufactured from premium-grade forged steel, chosen for its excellent strength-to-weight ratio and fatigue resistance. The rods undergo a rigorous heat treatment process to enhance durability under extreme operating conditions. The Straight Pro-H design ensures uniform load distribution along the rod, minimizing stress points and extending service life.

The 3/8-inch WMC bolts are engineered to provide superior clamping force, reducing the risk of bolt stretch or failure during high RPM operation. Each rod is CNC machined to exact specifications, ensuring perfect alignment and fitment within the engine assembly. This meticulous construction process guarantees consistent performance and reliability in demanding environments.

Installation & Fitment:

These connecting rods are designed as direct replacements for Dodge Hemi 5.7L and 6.1L engines, making installation straightforward for experienced engine builders. While professional installation is recommended to ensure proper torque settings and clearances, the rods fit standard rod journals and crankshaft configurations without the need for extensive modifications.

Proper balancing and assembly practices should be followed to maximize engine longevity and performance. These rods are compatible with a wide range of aftermarket pistons and fasteners designed for high-performance Hemi builds.
