Manley Performance H-Beam Connecting Rod Set

2011–2024 Chrysler 300, Jeep Grand Cherokee, Ram 1500/2500/3500, Dodge Challenger/Charger/Durango/Magnum, Jeep Wrangler, Jeep Wagoneer 5.7L, 6.1L, 6.4L HEMI V8 Engines

Part #: 14089-8

Overview

The Manley Performance H-Beam Connecting Rod Set is engineered specifically for Chrysler HEMI V8 engines, including the 5.7L, 6.1L, and 6.4L displacements found in a wide range of Chrysler, Jeep, Dodge, and Ram vehicles from 2011 through 2024. Designed for enthusiasts and professional builders alike, this set offers a robust upgrade over factory rods, delivering enhanced strength and durability to support increased power and higher RPM operation.

Ideal for street performance builds, spirited daily drivers, and mild race applications, these connecting rods provide a reliable foundation for engine upgrades without the premium cost of Manley’s top-tier lines. They maintain factory rod length and wrist pin diameter to ensure seamless compatibility with stock pistons and crankshafts, making them a straightforward choice for engine rebuilds and performance enhancements.

Key Features

Manley’s H-Beam connecting rods combine advanced materials and precision engineering to improve engine reliability and performance:

• Forged from high-strength steel alloy for exceptional durability and fatigue resistance under high loads
• H-Beam design optimizes strength-to-weight ratio, reducing reciprocating mass while maintaining rigidity
• 6.2-inch rod length tailored for Chrysler 5.7L, 6.1L, and 6.4L HEMI engines to preserve proper piston-to-crankshaft geometry
• 24mm wrist pin diameter for enhanced pin stability and load distribution
• Precision machined to tight tolerances for consistent fitment and balanced engine performance
• Includes ARP 8740 high-strength rod bolts for reliable clamping force and long-term durability
• Compatible with factory pistons and many aftermarket upgrades designed for these engine platforms

Construction & Design

Each connecting rod in this set is forged from premium-grade steel alloy, delivering excellent tensile strength and resistance to bending or twisting under extreme engine loads. The H-Beam cross-section provides an optimal balance of stiffness and reduced weight compared to traditional I-beam rods, enhancing engine response and durability.

Manley’s meticulous machining process ensures precise bore alignment and surface finish, critical for maintaining engine balance and performance. The use of ARP 8740 rod bolts further strengthens the rod-to-cap joint, maintaining clamping force even under high RPM and power conditions. This combination of materials and craftsmanship results in a connecting rod set capable of supporting high-performance builds while maintaining reliability and longevity.

Installation & Fitment

This set of eight connecting rods is designed as a direct replacement for Chrysler 5.7L, 6.1L, and 6.4L HEMI engines found in numerous Chrysler, Jeep, Dodge, and Ram models from 2011 to 2024. The rods fit factory pistons and crankshafts without modification, allowing for straightforward installation by experienced engine builders and professional shops.

No cutting, drilling, or special tuning is required, provided the engine block and related components are in good condition and compatible with the specified rod dimensions. The rods maintain factory rod length and wrist pin diameter, preserving proper engine geometry and balance. Included ARP 8740 rod bolts ensure secure fastening and long-term durability.

What's Included

• Set of 8 forged H-Beam connecting rods, 6.2 inches in length
• 24mm wrist pin diameter compatible rod ends
• High-strength ARP 8740 rod bolts pre-installed

Ideal For

• Performance enthusiasts upgrading Chrysler 5.7L, 6.1L, or 6.4L HEMI engines
• Street and track builds requiring durable, lightweight connecting rods
