Fits 5.7L, 6.1L, and 6.4L HEMI Engines

15057R-8

Overview:

Manley Performance’s H-Beam Connecting Rods are engineered for enthusiasts and builders seeking a reliable upgrade for their 5.7L, 6.1L, or 6.4L HEMI engines. Designed to deliver exceptional strength and durability, these rods provide a solid foundation for high-performance applications without breaking the bank.

Whether you’re building a street-driven muscle car, a weekend racer, or a high-output daily driver, these connecting rods offer the quality and consistency needed to support increased power and engine stress. You’ll get peace of mind knowing your rotating assembly is built to withstand demanding conditions.

Key Features:

These connecting rods combine advanced materials and precise manufacturing techniques to ensure long-lasting performance and reliability:

• Constructed from premium steel for superior strength and fatigue resistance.
• H-Beam design optimizes the balance between weight and rigidity, reducing flex under high loads.
• 6.125-inch center-to-center length, ideal for 5.7L, 6.1L, and 6.4L HEMI engine configurations.
• Compatible with .866-inch wrist pins for precise fitment and durability.
• Includes high-quality ARP2000 rod bolts, known for their excellent tensile strength and reliability.
• Manufactured to the same exacting standards as Manley’s Sportsmaster® and Pro Series rods, ensuring consistent quality.
• Designed to handle increased horsepower and torque demands in performance and racing applications.
• Set of 8 rods, perfect for V8 engine builds requiring a full rotating assembly upgrade.

Construction & Design:

Manley’s H-Beam rods are precision-machined from high-grade steel, providing an optimal combination of strength and weight savings. The H-Beam cross-section enhances rigidity and reduces bending stress during high-RPM operation, which helps maintain engine reliability under extreme conditions.

Each rod is carefully balanced and inspected to meet strict quality control standards. The inclusion of ARP2000 rod bolts ensures secure fastening with superior tensile strength, reducing the risk of fastener failure during aggressive driving or racing.

Installation & Fitment:

These connecting rods are designed as direct replacements for factory rods in 5.7L, 6.1L, and 6.4L HEMI engines. They fit standard engine configurations using .866-inch wrist pins and 6.125-inch rod length, making them compatible with many common HEMI builds.

Installation requires standard engine assembly procedures. No modifications to the engine block or crankshaft are necessary when upgrading to these rods, provided the engine is built to compatible specifications.

What's Included:

• Set of 8 Manley H-Beam steel connecting rods
• ARP2000 high-strength rod bolts pre-installed

Ideal For:

• Performance enthusiasts upgrading their HEMI V8 engines
• Street and strip muscle cars requiring durable rotating assembly components
• Engine builders seeking a cost-effective, high-quality connecting rod solution
• Applications demanding reliable strength for increased horsepower and torque

Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
