Overview:
Manley Performance’s Pro Series I-Beam Connecting Rod Set is engineered to deliver exceptional strength, precision, and reliability for your Chrysler 5.7L HEMI engine. Designed for performance enthusiasts and engine builders seeking to upgrade their bottom end, these connecting rods provide a solid foundation for increased power and durability.
Whether you are building a high-performance street engine or a track-focused powerplant, this connecting rod set helps you push your engine’s capabilities while maintaining dependable operation under demanding conditions. The included ARP 625+ head stud kit further enhances the integrity of your cylinder head fastening system, ensuring consistent clamping force and improved sealing.
Key Features:
These connecting rods and head studs incorporate advanced materials and manufacturing techniques to optimize performance and longevity:
Construction & Design:
Manley’s Pro Series connecting rods feature a standard I-beam profile forged from premium steel, providing an excellent strength-to-weight ratio. The rods undergo a finely tuned manufacturing process that includes precision machining and quality control inspections to ensure consistent performance and durability.
The ARP 625+ head studs included in this kit are manufactured from a proprietary alloy that offers superior tensile strength compared to standard studs. This material choice helps maintain consistent clamping force under high-stress conditions, reducing the risk of head gasket failure and improving overall engine reliability.
Installation & Fitment:
This connecting rod set is designed as a direct replacement for the Chrysler 5.7L HEMI engine’s factory rods, matching the standard 6.125-inch rod length for proper piston-to-crank geometry. Installation requires standard engine assembly procedures and is best performed by experienced engine builders or professionals.
No modifications to the engine block or crankshaft are necessary when installing these rods. The included ARP 625+ head studs fit directly into the factory cylinder head bolt holes, providing a straightforward upgrade to your engine’s fastening system.
What's Included:
Ideal For:
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
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!
