Manley Performance Race Master Exhaust Valves are precision-engineered for the demanding 6.4L HEMI engines found in Chrysler, Dodge, Jeep, and Ram vehicles from 2011 through 2024. Designed specifically for high-performance and racing applications, these valves excel in extreme conditions such as bracket racing, drag racing, and oval track competition. Built to withstand engine speeds up to 8000 RPM, they offer enhanced durability and reliability for serious racers and performance enthusiasts seeking to upgrade or rebuild their exhaust valve train components.
Whether you are assembling a race motor or improving factory components for increased longevity and consistent performance, Manley’s Race Master valves provide race-proven quality and precision fitment tailored to the 6.4L HEMI platform.
Manley Race Master Exhaust Valves combine advanced materials and design innovations to meet the rigorous demands of high-revving engines. Key features include:
These exhaust valves are crafted from high-grade materials selected to endure the intense heat and mechanical stresses typical of racing environments. The triple groove configuration ensures a secure fit with valve springs, minimizing the risk of valve failure during high-RPM operation. Precision machining maintains tight dimensional tolerances, promoting optimal sealing and combustion chamber efficiency. This meticulous construction supports improved engine reliability and longevity, even under the demanding conditions of competitive motorsports.
Manley Race Master Exhaust Valves are designed as direct replacements for factory valves in 2011 and newer Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 6.4L 392 HEMI engine. Installation follows standard engine rebuild procedures and is best performed by experienced technicians or engine builders familiar with high-performance valve train components. No modifications to the cylinder head or valve train are necessary when installed correctly. These valves are engineered to perform reliably at engine speeds up to 8000 RPM.
This valve set is perfect for racers and performance enthusiasts who demand durability and reliability in high-RPM applications. 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!
