Key Features:

This rotating assembly combines high-quality components to provide a robust foundation for your 6.1L HEMI build:

• 4.050" forged 4340 steel crankshaft for exceptional strength and durability
• 32 tooth reluctor wheel designed for modern ignition systems
• 6.125" H-beam connecting rods crafted from forged materials for superior tensile strength
• 7/16" ARP 8740 rod bolts to ensure secure rod-to-crank connections under high stress
• Forged 4032 Mahle pistons with -12cc inverted dome design and 4.065" 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 load capacity and durability

Construction & Design:

The assembly features a forged 4340 steel crankshaft, known for its toughness and resistance to fatigue, making it suitable for racing and forced induction applications. The 6.125" H-beam rods are forged for maximum strength and rigidity, paired with premium ARP 8740 bolts to maintain integrity under extreme RPM and torque loads.

Mahle forged pistons crafted from 4032 alloy provide a lightweight yet durable solution, with an inverted dome design that optimizes compression and combustion efficiency. The plasma-moly file-fit rings ensure a precise seal within the cylinder bore, reducing blow-by and improving oil control. King XP bearings complete the assembly, offering enhanced durability and performance under high-stress conditions.

Installation & Fitment:

This rotating assembly is designed specifically for the Chrysler 6.1L HEMI engine and requires professional balancing by a qualified machine shop prior to installation to ensure optimal performance and longevity. Proper balancing is critical to prevent vibrations and premature wear. Installation should be performed by experienced engine builders familiar with high-performance rotating assemblies and Chrysler HEMI engines.
