Construction & Design:
This crankshaft is meticulously forged from 4340 steel, a material known for its excellent fatigue resistance and tensile strength, making it a preferred choice for high-performance engine components. The forging process enhances the grain structure of the steel, resulting in a crankshaft that can endure the rigors of high RPMs and increased cylinder pressures.
The internal balance design reduces harmonic vibrations, contributing to smoother engine operation and improved longevity of related components. Additionally, the lightened construction reduces rotational inertia, allowing the engine to rev more freely and respond quicker to throttle inputs.
Installation & Fitment:
The Callies Compstar crankshaft is designed to fit a broad range of 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 and must be sourced separately. Rod and main bearings are also sold separately, allowing builders to select bearings that best suit their application.
Installation should be performed by a qualified engine builder or technician to ensure proper clearances and alignment. The crankshaft’s 1-piece rear main seal style and standard snout ensure compatibility with OEM seals and accessories, simplifying the swap process.
What's Included:
- One forged 4340 steel crankshaft
- Mechanical and electrical failure coverage plan
Ideal For:
This crankshaft is ideal for performance enthusiasts, engine builders, and professional racers upgrading or rebuilding Chrysler, Dodge, Jeep, and Ram Hemi engines. It is well-suited for applications requiring enhanced durability and strength, including street performance, drag racing, road racing, and off-road builds where reliability under high stress is critical.
Callies Performance is known for high-end rotating-assembly components—especially crankshafts and connecting rods—built for serious horsepower and demanding race conditions.

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!
