11695B-8

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 demands of bracket racing, drag racing, and oval track competition, these valves deliver reliable durability and consistent performance for engines operating up to 8000 RPM.

If you are a racer or enthusiast looking to upgrade your engine’s valvetrain with components built for endurance and efficiency, these Manley valves provide an excellent balance of strength and flow characteristics. They help ensure optimal exhaust gas evacuation, which supports improved engine breathing and overall power delivery.

Key Features:

Manley Race Flo Exhaust Valves incorporate advanced design and manufacturing techniques to meet the rigorous requirements of motorsports applications. Key features include:

• Constructed from high-strength materials engineered for durability under high RPM and extreme thermal conditions.
• Bead Loc Groove design enhances valve retention and stability during aggressive engine operation.
• Optimized valve face and stem dimensions tailored for the Chrysler 5.7L HEMI exhaust port to maximize flow and reduce turbulence.
• Precision machining ensures tight tolerances for consistent sealing and long service life.
• Race Flo design promotes improved exhaust gas evacuation, supporting better combustion efficiency and power output.
• Set of 8 valves included, sufficient for a complete V8 exhaust valve upgrade.

Construction & Design:

Each valve is manufactured with a focus on strength and reliability, using premium-grade alloys suited for high-performance racing environments. The Bead Loc Groove feature is a critical design element that secures the valve spring retainer more effectively, reducing the risk of valve float or failure at elevated RPMs. The valves are precision ground and heat-treated to withstand the thermal and mechanical stresses typical of competitive racing engines.

This meticulous construction ensures that your Chrysler HEMI 5.7L engine maintains optimal exhaust flow characteristics while enduring the harsh conditions of bracket and drag racing.

Installation & Fitment:

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

No special machining or alterations are required beyond standard valve installation procedures. Proper valve job and engine assembly practices should be followed to ensure optimal performance and longevity.
