Key Features:

Built with premium materials and designed for high-stress environments, this rotating assembly offers a range of features that enhance engine durability and performance:

• 4.050" forged 4340 steel crankshaft for superior strength and fatigue resistance
• 32 tooth reluctor wheel for precise ignition timing and compatibility with modern engine management systems
• 6.125" H-beam connecting rods constructed from high-strength materials for improved rod stability
• 7/16" ARP 8740 rod bolts providing exceptional clamping force and reliability
• Forged 4032 Mahle flat-top pistons with a 3.947" bore size and -2cc dish for optimized compression
• Plasma-moly file-fit piston rings for excellent sealing and reduced friction
• King XP rod and main bearings engineered for high load capacity and durability
• Precision balanced components (assembly requires balancing by a qualified machine shop prior to installation)

Construction & Design:

This rotating assembly is crafted from premium forged materials to ensure maximum strength and longevity. The 4340 forged steel crankshaft offers excellent resistance to twisting and bending forces, making it ideal for high-horsepower applications. The 6.125" H-beam rods are designed to handle increased cylinder pressures while maintaining lightweight characteristics to reduce reciprocating mass.

Mahle forged pistons made from 4032 alloy provide superior thermal stability and strength, while the plasma-moly rings are file-fit for a perfect seal and minimal blow-by. The use of King XP bearings further enhances durability under extreme operating conditions. The 32 tooth reluctor wheel is precision-machined to maintain accurate engine timing signals, critical for modern ignition and fuel injection systems.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 5.7L HEMI engine platform. It is intended for professional installation and requires balancing by a qualified machine shop before use to ensure optimal engine performance and longevity. Proper balancing is critical to prevent premature wear and vibration issues. Installation should be performed by experienced engine builders familiar with high-performance rotating assemblies.
