The Eagle 5.7L Modern Hemi 58 Tooth Reluctor Rotating Assembly is engineered for high-performance applications, including all forms of racing such as nitrous-boosted and forced-induction setups. This premium rotating assembly combines strength, durability, and precision to handle the increased stresses of competitive environments. Designed specifically for the Chrysler 5.7L HEMI engine, it offers a robust foundation for engine builders seeking reliable power and longevity under extreme conditions.

Built with race-ready components, this assembly is ideal for enthusiasts and professional racers who demand uncompromising quality and performance from their rotating assemblies. It requires professional balancing by a qualified machine shop prior to installation to ensure optimal engine operation and longevity.

Key Features:

This rotating assembly integrates high-grade materials and advanced engineering to deliver exceptional strength and durability. Key features include:

• 4.050" forged 4340 steel crankshaft for superior strength and fatigue resistance
• 58 tooth reluctor wheel compatible with modern ignition systems
• 6.125" H-beam connecting rods crafted for high-load endurance
• 7/16" ARP 8740 rod bolts for enhanced clamping force and reliability
• Forged 4032 Mahle pistons with -2cc flat top design and 3.937" bore size for optimal combustion chamber volume
• Plasma-moly file-fit piston rings for excellent sealing and reduced friction
• King XP rod and main bearings engineered for high-performance durability
• Precision machined components requiring professional balancing before use

Construction & Design:

The assembly is constructed using premium forged materials selected for their strength and resistance to wear under high-stress conditions. The 4340 forged steel crankshaft offers exceptional toughness and fatigue resistance, essential for racing and forced-induction applications. The 6.125" H-beam rods provide a perfect balance of rigidity and weight savings, ensuring reliable power transfer without compromising durability.

Mahle forged pistons made from 4032 alloy feature a -2cc flat top design that optimizes compression and combustion efficiency. Plasma-moly file-fit rings are carefully fitted to reduce blow-by and maintain oil control, enhancing engine longevity. The use of ARP 8740 rod bolts further increases the assembly’s ability to withstand high RPM and boost pressures.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 5.7L HEMI engine platform. Installation requires a qualified machine shop to perform dynamic balancing to ensure smooth engine operation and prevent premature wear. Proper balancing is critical to maximize performance and reliability, especially in high-RPM or forced-induction applications.

While the assembly is a direct fit for the 5.7L HEMI, professional installation and engine blueprinting are recommended to achieve the best results and maintain engine longevity.

What's Included:

• 4.050" forged 4340 steel crankshaft with 58 tooth reluctor
• 6.125" forged H-beam connecting rods
• Forged 4032 Mahle -2cc flat top pistons (3.937" bore)
• Plasma-moly file-fit piston rings
• King XP rod and main bearings
• 7/16" ARP 8740 rod bolts

Ideal For:

This rotating assembly is ideal for racers, engine builders, and performance enthusiasts who are upgrading or rebuilding Chrysler 5.7L HEMI engines for high-horsepower applications. It is particularly well-suited for vehicles running nitrous oxide, turbochargers, superchargers, or other forms of forced induction where durability and precision are paramount.

Eagle Specialty Products manufactures high-strength engine components—most notably connecting rods and crankshafts—intended for performance and racing engines. These rotating-assembly upgrades are commonly used in builds that demand higher strength margins for boost, nitrous, sustained RPM, or competition use.
