The Manley Performance Race Master Exhaust Valve Set is engineered specifically for the Chrysler 6.4L 392 HEMI engine, covering model years 2011 through 2024. Designed for high-performance racing applications, these exhaust valves deliver exceptional durability and reliability under extreme conditions. Whether you’re building a bracket racer, drag car, or oval track machine, these valves provide the strength and precision needed to support aggressive cam profiles and engine speeds up to 8000 RPM.
Built to withstand the intense heat and stress of competitive motorsports, Manley’s Race Master valves help maintain optimal exhaust flow and valve sealing, ensuring consistent performance and extended valve life. This set of eight valves is ideal for complete engine rebuilds or performance upgrades on Chrysler 6.4L HEMI-powered vehicles.
Manley’s Race Master Exhaust Valves incorporate advanced engineering and materials to meet the demands of high-RPM racing environments:
Manley’s Race Master Exhaust Valves are crafted from high-grade materials selected for their exceptional heat resistance and wear properties, essential for high-performance racing engines. The valves feature a robust stem and head design engineered to maintain structural integrity at elevated engine speeds and temperatures.
The 1.654-inch valve head diameter is carefully matched to the Chrysler 6.4L HEMI exhaust port dimensions, promoting efficient exhaust gas evacuation and improved engine breathing. Precision machining and stringent quality control ensure each valve meets exacting tolerances for optimal fit, sealing, and durability.
These exhaust valves are designed as direct replacements for the Chrysler 6.4L 392 HEMI engine exhaust valves found in a wide range of vehicles from 2011 to 2024. They fit seamlessly into the factory valve guides and seats, allowing for straightforward installation by experienced engine builders and machinists. No modifications to the cylinder head or valve train components are typically required when upgrading to these valves.
Compatible vehicles include:
This valve set is perfect for racers, engine builders, and performance enthusiasts focused on maximizing the durability and efficiency of Chrysler 6.4L HEMI race engines. It is especially suited 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!
