Key Features:
This rotating assembly kit combines high-quality materials and meticulous craftsmanship to deliver dependable performance. Key features include:
- Forged 4340 steel crankshaft for superior strength and durability
- Forged 4340 steel H-beam connecting rods, 6.125 inches center-to-center length
- Forged aluminum pistons with dome design and two valve reliefs for optimized combustion
- Pistons and rings oversized by 0.030 inches (0.760mm) for precise bore fitment
- Plasmamoly piston ring facing material for enhanced wear resistance and sealing
- Floating wrist pins for reduced friction and improved piston articulation
- Complete set of rod and main bearings included at stock undersizes for easy installation
- Balanced internal engine components (excluding external balancing)
- Designed specifically for a 6.5L/396 engine displacement with a 3.947-inch bore and 4.050-inch stroke
Construction & Design:
The kit’s core components are crafted from premium forged materials to withstand the rigors of high-performance use. The crankshaft and connecting rods utilize 4340 forged steel, known for its exceptional tensile strength and fatigue resistance. The pistons are forged aluminum, providing a lightweight yet robust design that supports high RPM operation and thermal stability.
The piston design features a dome shape with two valve reliefs, optimizing combustion chamber dynamics and valve clearance. The use of plasmamoly for piston ring facings enhances durability and reduces wear under extreme conditions. Each component is manufactured to tight tolerances to ensure proper fitment and long-term reliability.
Installation & Fitment:
This rotating assembly kit is designed for direct fitment in most Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including performance variants such as the 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk. It is compatible with engines utilizing a 58-tooth reluctor wheel.
Installation requires professional engine assembly knowledge and proper machining of the engine block to accommodate the 0.030-inch oversized pistons and rings. Note that this kit does not include external components such as harmonic balancer, flexplate, flywheel, camshaft, lifters, timing chain, gears, gaskets, or oil pump, which must be sourced separately.
What's Included:
- Forged 4340 steel crankshaft
- Forged 4340 steel H-beam connecting rods (6.125" center-to-center)
- Forged aluminum dome pistons with two valve reliefs (0.030" oversize)
- Piston rings with plasmamoly facing
- Rod bearings (stock undersize)
- Main bearings (stock undersize)
Ideal For:
This kit is perfect for engine builders, performance enthusiasts, and professional shops aiming to build or rebuild Chrysler and Dodge Hemi engines with enhanced durability and reliability. It suits applications ranging from street performance to moderate track use where a strong rotating assembly is critical.
