Eagle Rotating Assembly
Multiple Chrysler Fitments
234044090
Overview:
The Eagle Rotating Assembly is a high-performance engine component package designed for multiple Chrysler applications. This assembly combines precision-engineered parts to deliver enhanced durability, strength, and reliability for serious engine builds. Ideal for enthusiasts and professional builders seeking to upgrade or rebuild their Chrysler engines, this rotating assembly offers a balanced combination of forged materials and advanced engineering to withstand demanding conditions.
Whether you are building a street performance engine or a race-ready powerplant, this assembly provides the core components needed to improve engine response, longevity, and overall performance. Its robust construction ensures consistent operation under high RPM and load scenarios.
Key Features:
This rotating assembly includes carefully selected components that work together to optimize engine performance and durability:
- 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-stress applications
- 7/16" ARP 8740 rod bolts providing exceptional clamping force and reliability
- Forged 2618 aluminum DSS 4cc dome pistons with a 4.090" bore size for improved combustion efficiency
- Plasma-moly file-fit piston rings designed for optimal sealing and reduced friction
- King XP rod and main bearings engineered for enhanced wear resistance and load capacity
Construction & Design:
The Eagle Rotating Assembly is built with premium materials and precision manufacturing processes. The forged 4340 steel crankshaft offers excellent toughness and resistance to twisting forces, making it suitable for high-performance and racing engines. The 6.125" H-beam rods are designed to handle increased cylinder pressures while maintaining lightweight characteristics to reduce reciprocating mass.
The pistons are forged from 2618 aluminum alloy, known for its strength and thermal stability, and feature a 4cc dome to optimize compression ratios. Plasma-moly coated rings are file-fit to ensure a perfect seal, reducing blow-by and oil consumption. King XP bearings provide a durable interface between the rotating assembly and engine block, ensuring smooth operation under extreme conditions.
Installation & Fitment:
This rotating assembly is engineered to fit multiple Chrysler engines, making it a versatile choice for various rebuilds and performance upgrades. Installation requires standard engine assembly procedures and precise torque specifications, especially for the ARP rod bolts. It is recommended that installation be performed by experienced technicians or engine builders to ensure proper clearances and alignment.
No major modifications are typically necessary, but verification of fitment and compatibility with your specific engine model is advised before installation.
What's Included:
- Forged 4340 4.050" crankshaft with 58-tooth reluctor
- 6.125" H-beam connecting rods
