The crankshaft and connecting rods are forged from 4340 steel, a high-strength alloy known for its toughness and resistance to stress and fatigue. This ensures the assembly can handle high RPMs and increased power outputs typical of modern muscle engines.\u003c\/p\u003e\u003cp\u003eThe pistons are forged from lightweight aluminum alloy, featuring a dished crown with valve reliefs to maintain proper clearance and optimize combustion efficiency. The use of plasmamoly piston rings enhances durability and maintains excellent sealing under extreme conditions. The floating wrist pins reduce wear and friction, contributing to smoother engine operation and longevity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; Fitment:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis kit is designed as a direct fit for Chrysler, Dodge, Jeep, and Ram engines with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat \u0026amp; Trackhawk configurations.
