What is the stroke length of this crankshaft?

This Manley crankshaft features a 4.050-inch stroke. This increased stroke is what allows for the significant increase in engine displacement when installed.

What is the purpose of the 58-tooth reluctor wheel?

The 58-tooth reluctor wheel is a critical component for the engine's computer to accurately read engine speed and position. It is specifically designed for compatible Hemi engine management systems.

What is the benefit of the 4340 alloy steel construction?

Forging from 4340 alloy steel provides a strong and durable foundation for the crankshaft. This material is chosen for its ability to withstand the high stresses and temperatures found in performance and racing engines.

About this part

Product Details

If you're building a high-performance Hemi engine for your Chrysler, a strong crankshaft is the heart of the operation. This Manley Pro Series crankshaft is forged from 4340 alloy steel, making it a well-built foundation for serious power. It's designed to handle the demands of increased displacement, turning your 5.7L into a 392 cubic inch powerhouse or your 6.1L/6.4L into a 426 cubic inch monster.

Manley puts this crankshaft through a multi-step heat treatment and nitriding process to significantly boost its strength and ensure it lasts. The journals are micro-polished with large radii to cut down on friction, which helps improve overall performance. To ensure it's ready for the stress of high RPMs and significant power, each crankshaft is stress relieved, shot peened, and 100% magnafluxed to meet Manley's strict quality standards. The gun-drilled mains and lightened rod journals also contribute to a lighter rotating assembly, which can help optimize engine performance and stability.

This crankshaft features a 4.050-inch stroke, which is key to increasing your engine's displacement. It also comes with a 58-tooth reluctor wheel, essential for proper engine management on compatible Hemi platforms. When you're aiming for a significant power increase and need a reliable core component, this forged crankshaft is a solid option.
