Manley 4340 Forged Crankshaft for Chrysler 5.7L/6.1L Hemi Engines

Transform your Chrysler Hemi engine with the Manley 4340 Forged Crankshaft, engineered for maximum performance and durability. This premium crankshaft features an increased stroke and robust construction, making it the perfect foundation for building a high-horsepower naturally aspirated or forced induction powerhouse.

Unleash Hemi Power:

  • 4340 Steel Forging: Provides superior strength and reliability to handle significantly increased power levels.
  • 4.050" Stroke: Increases displacement, turning a 5.7L into a 392ci or a 6.1L/6.4L into a 426ci engine for dramatic power gains.
  • Lightweight Design: Features gun-drilled mains and lightened rod journals to reduce rotating mass, enhancing engine responsiveness and RPM capability.
  • Profiled Counterweights: Precisely balanced for smooth operation and reduced stress on the engine.
  • Micro-Polished Journals: Large radius journals are polished for reduced friction and wear, improving efficiency.
  • Enhanced Strength: Undergoes a multi-step heat treatment process and nitriding for superior hardness and longevity.
  • 58 Tooth Reluctor Wheel: Includes a 58-tooth reluctor wheel for compatibility with modern Hemi engine management systems.
  • Rigorous Quality Assurance: Each crankshaft is stress relieved, shot peened, and 100% magnafluxed for guaranteed quality.

This Manley crankshaft is an essential upgrade for any serious Hemi enthusiast looking to push the boundaries of performance. Its superior materials and design ensure it can withstand the rigors of high-performance driving and racing.
