Key Features:
This crankshaft combines advanced materials and precision engineering to meet the demands of high-output Hemi engines. Key features include:
- Forged 4340 steel construction for superior strength and durability
- 3.800-inch stroke optimized for increased displacement and torque
- Internal engine balance for smooth and reliable operation
- Lightened design reduces rotating mass, enhancing throttle response
- Standard crankshaft snout style for compatibility with OEM components
- Requires narrow bearings for proper fitment
- Rod journal diameter of 2.100 inches and main journal diameter of 2.559 inches
- 1-piece rear main seal style for simplified sealing and maintenance

Construction & Design:
The Callies Compstar crankshaft is meticulously forged from 4340 chromoly steel, a material renowned for its high tensile strength and resistance to wear and fatigue. This forging process ensures a dense, uniform grain structure, providing enhanced durability under extreme loads. The crankshaft undergoes precision machining to exact tolerances, ensuring optimal journal finishes and dimensional accuracy for reliable bearing fitment and long service life.
Its internal balance design reduces vibrations and stress on engine components, contributing to smoother operation and improved longevity. The lightened crankshaft design minimizes rotational inertia, allowing the engine to rev more freely and respond quicker to throttle inputs.
Installation & Fitment:
This crankshaft is designed as a direct fit replacement for most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires the use of narrow bearings, which are not included, so ensure proper bearing selection for your build. Rod bearings and main bearings are also sold separately.
Professional installation is recommended to ensure proper torque specifications and clearances are met. The crankshaft’s standard snout style allows compatibility with factory harmonic balancers and timing components, simplifying the upgrade process.
What's Included:
- One forged 4340 steel crankshaft
- Mechanical and electrical failure coverage plan

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
