Crafted for enthusiasts and professional builders alike, these connecting rods deliver exceptional strength and reliability under high-stress conditions. Whether upgrading a street machine or building a race engine, these rods provide the durability and consistency required to handle increased power and RPM demands.

Built to exacting standards, the Straight Pro-H rods are ideal for those seeking to enhance engine longevity while maintaining optimal weight and balance. Their robust construction ensures dependable operation in demanding environments, making them a trusted choice for Dodge Hemi performance upgrades.

Key Features:

These connecting rods incorporate advanced design and manufacturing techniques to maximize performance and durability. Key features include:

• High-strength 3/8" WMC (Wide Male Cap) bolts for superior clamping force and fatigue resistance
• Straight Pro-H design optimized for Dodge Hemi 5.7L and 6.1L engines
• Precision CNC machining for exact tolerances and perfect fitment
• Lightweight yet durable construction to reduce reciprocating mass and improve engine response
• Heat-treated and shot-peened for enhanced fatigue life and reliability
• Balanced for smooth operation and reduced vibration
• Compatible with factory and aftermarket pistons and crankshafts
• Engineered to withstand high horsepower and high RPM applications

Construction & Design:

Carrillo connecting rods are manufactured from premium forged steel alloys, chosen for their exceptional strength-to-weight ratio and fatigue resistance. The forging process ensures a dense, uniform grain structure that enhances durability under extreme loads. Each rod undergoes rigorous CNC machining to achieve precise dimensions and surface finishes, critical for maintaining engine balance and performance.

The 3/8" WMC bolts are a standout feature, providing a wider bearing surface and increased clamping force compared to standard bolts. This design reduces the risk of bolt stretch or failure during high-stress operation. Additionally, the rods are heat-treated and shot-peened to relieve internal stresses and improve resistance to cracking and wear.

Installation & Fitment:

These connecting rods are designed as direct replacements for Dodge Hemi 5.7L and 6.1L engines, requiring no modifications for proper installation. They fit seamlessly with factory crankshafts and pistons, making them an excellent upgrade for rebuilds or performance builds. Professional installation is recommended to ensure proper torque specifications and clearances are met for optimal engine reliability.
