Designed to withstand the rigors of nitrous and forced-induction applications, this assembly delivers exceptional strength and durability under extreme conditions. Whether you’re building a street machine or a dedicated race engine, this rotating assembly provides the foundation for reliable, high-revving performance.

Built with premium forged components and precision machining, the Eagle rotating assembly ensures consistent power delivery and engine longevity. It is ideal for racers and performance builders who demand a balance of strength, weight savings, and precision fitment in their bottom-end components.

Key Features:

This rotating assembly incorporates advanced materials and design features to optimize performance and durability:

• 4.050" forged 4340 steel crankshaft for superior strength and fatigue resistance
• 58 tooth reluctor wheel for modern ignition and engine management compatibility
• 6.125" forged H-beam connecting rods for enhanced tensile strength and reduced weight
• 7/16" ARP 8740 rod bolts for maximum clamping force and reliability
• Forged 4032 Mahle pistons with 6cc dome and 3.947" compression height for precise combustion chamber control
• Plasma-moly file-fit piston rings for excellent sealing and reduced friction
• King XP rod and main bearings engineered for high-load durability and smooth operation
• Balanced assembly ready for final machine shop balancing to ensure smooth engine operation

Construction & Design:

The Eagle rotating assembly is meticulously crafted from premium forged materials to withstand the extreme stresses of high-performance and racing environments. The 4340 forged steel crankshaft offers exceptional toughness and resistance to twisting forces, while the forged 4032 alloy pistons provide excellent thermal stability and strength. The 6.125" H-beam rods are designed to handle high RPM and boost levels without compromising reliability.

Each component is precision machined and assembled with tight tolerances to ensure optimal fit and function. The use of ARP 8740 bolts enhances the structural integrity of the rod assemblies, preventing fastener stretch or failure under high load. Plasma-moly piston rings are file-fit for a custom seal, reducing blow-by and improving efficiency.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 5.7L HEMI engine platform. It is supplied as a complete rotating assembly but must be balanced by a qualified machine shop prior to installation to ensure proper engine balance and smooth operation. Installation requires standard engine assembly procedures and attention to detail to achieve optimal performance and durability.

Builders should verify clearances and compatibility with their specific engine block and cylinder head configurations. This assembly is ideal for custom engine builds where reliability and strength are paramount.

What's Included:

• 4.050" forged 4340 steel crankshaft with 58 tooth reluctor
• 6.125" forged H-beam connecting rods
• 7/16" ARP 8740 rod bolts
• Forged 4032 Mahle 6cc dome pistons (3.947" compression height)
• Plasma-moly file-fit piston rings
• King XP rod and main bearings

Ideal For:

This rotating assembly is ideal for performance engine builders and racers who require a durable, high-strength bottom end for Chrysler 5.7L HEMI engines.
