Manley Performance Race Master Exhaust Valves are precision-engineered for Chrysler 5.7L HEMI engines produced from 2003 through 2008. Designed to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these valves deliver exceptional durability and consistent performance at engine speeds up to 8,000 RPM. Whether you are rebuilding a race-prepped engine or upgrading for improved exhaust flow and valve longevity, Manley’s Race Master valves provide the reliability and strength essential for high-performance applications.
Built to withstand extreme heat and mechanical stress, these valves help maintain optimal engine efficiency and power output under the toughest racing conditions. They are an ideal choice for racers and performance enthusiasts seeking a direct-fit, high-quality exhaust valve solution for their Chrysler HEMI 5.7L engines.
Manley Race Master Exhaust Valves incorporate advanced design and manufacturing techniques tailored for serious racers and performance builders. Key features include:
Manley’s Race Master valves feature a robust construction designed specifically for high-performance exhaust applications. The triple groove stem enhances valve guide retention, reducing the risk of valve float or misalignment during high-RPM operation. Precision machining from premium, heat-resistant materials ensures these valves withstand the intense thermal and mechanical stresses encountered in racing.
The 1.555-inch stem diameter strikes a balance between durability and smooth valve train operation, contributing to improved stability and longevity. These valves maintain optimal sealing and exhaust flow characteristics, which are critical for maximizing power and efficiency in demanding motorsports environments.
These exhaust valves are direct replacements for factory components in Chrysler 5.7L HEMI engines built from 2003 to 2008. They fit standard valve guides and seats designed for this engine family, allowing straightforward installation by experienced engine builders and machinists. Proper valve job and seat preparation are recommended to ensure optimal sealing and performance.
No modifications to the cylinder head or valve train are required when installing these valves, provided the engine falls within the specified application range. These valves are intended for use in performance or race engines and should be installed by professionals familiar with high-performance valvetrain assembly.
These valves fit the following vehicles equipped with the 5.7L HEMI engine:
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!
