Overview:

The Manley Race Series Exhaust Valves are precision-engineered components designed specifically for high-performance Chrysler HEMI 5.7L engines from 2009 onward. Crafted to withstand the intense conditions of bracket racing, drag racing, and oval track competition, these valves deliver reliable durability and enhanced exhaust flow for engines operating up to 8,000 RPM.

Whether you are a serious racer or a performance enthusiast looking to upgrade your engine’s valvetrain, these valves provide the strength and efficiency needed to support aggressive cam profiles and high RPM operation. Installing Manley Race Series valves helps ensure your engine maintains optimal performance and longevity under demanding conditions.

Key Features:

Manley’s Race Series Exhaust Valves incorporate advanced design and materials to meet the rigorous requirements of motorsports applications. Key features include:

• Constructed from high-strength, heat-resistant alloy steel for superior durability and resistance to valve seat recession.
• Triple groove design on the valve stem to enhance valve guide retention and reduce valve stem movement under high RPM.
• 2.050-inch valve head diameter optimized for improved exhaust gas flow and efficient scavenging in the 5.7L HEMI cylinder head.
• Precision ground and finished to exacting tolerances for consistent sealing and reliable operation.
• Engineered specifically for Chrysler HEMI 5.7L engines, ensuring proper fitment and compatibility with factory valve seats and guides.
• Ideal for engines running up to 8,000 RPM, supporting aggressive camshaft profiles and high-performance valvetrain setups.
• Designed to withstand the thermal and mechanical stresses of bracket, drag, and oval track racing environments.

Construction & Design:

Manley Race Series valves are manufactured using premium alloy steels selected for their high-temperature strength and wear resistance. The triple groove stem design improves valve guide retention, reducing the risk of valve wobble and wear during high-RPM operation. The valves are precision machined and heat treated to maintain dimensional stability and sealing integrity under extreme conditions.

The 2.050-inch valve head diameter is optimized for the exhaust ports of the 5.7L HEMI engine, promoting efficient exhaust gas evacuation and contributing to improved engine breathing and performance. This combination of materials, design, and manufacturing quality ensures these valves deliver reliable performance in demanding racing applications.

Installation & Fitment:

These valves are direct replacements for the factory exhaust valves in 2009 and newer Chrysler HEMI 5.7L engines. They are designed to fit OEM valve guides and seats without modification, making installation straightforward for experienced engine builders and racers.

No special machining or custom fitting is typically required, but proper valve job and seat preparation are recommended to ensure optimal sealing and longevity. These valves are intended for high-performance and racing use, so professional installation and valvetrain setup are advised.
