Part #: 46122-8
The Manley Ductile Iron Top Ring Set is engineered for enthusiasts and professional builders seeking a durable, reliable sealing solution for high-performance HEMI and SRT8 engines. Designed to fit a range of 5.7L and 6.1L V8 engines found in Chrysler 300C, Dodge Magnum, Dodge Charger, and Jeep Grand Cherokee models from 2005 to 2008, this ring set ensures optimal compression and oil control under demanding conditions.
Manley Performance’s commitment to quality and precision manufacturing makes this top ring set an excellent choice for engine rebuilds, upgrades, or performance enhancements where longevity and consistent sealing are critical.
Manley’s Ductile Iron Top Ring Set combines advanced materials and design to deliver superior performance and durability. Key features include:
The top rings are crafted from ductile iron, a material known for its toughness and ability to withstand high combustion pressures and temperatures. The plasma-moly inlay enhances the ring face by providing a hard, low-friction surface that reduces wear on both the ring and cylinder wall. This combination ensures a tight seal, improved oil control, and extended service life compared to conventional cast iron rings.
Manley’s precision engineering and quality control processes guarantee that each ring meets strict dimensional and material standards, ensuring consistent performance and compatibility with factory and aftermarket pistons.
This ring set is designed for direct fitment on 100mm bore Chrysler 5.7L and 6.1L HEMI and SRT8 engines found in the following vehicles:
Installation requires standard piston ring fitting procedures, including proper ring gap measurement and orientation. No modifications to the engine block or pistons are typically necessary when replacing with this Manley ring set, making it suitable for both professional engine builders and experienced enthusiasts.
This Manley Ductile Iron Top Ring Set is ideal for performance enthusiasts, engine builders, and mechanics working on Chrysler 5.7L and 6.1L HEMI or SRT8 engines who demand reliable sealing and durability. Whether rebuilding a street-driven muscle car or upgrading a track-focused build, these rings provide a solid foundation for maintaining compression and engine efficiency under increased loads and higher RPMs.
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!
