The Manley Performance Race Master Exhaust Valve Set is engineered specifically for Chrysler 6.1L HEMI engines from 2005 to 2010, delivering exceptional durability and performance for high-revving applications. Designed to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these valves provide reliable operation at engine speeds up to 8000 RPM. Whether you are a dedicated racer or a performance enthusiast upgrading your valvetrain, this set offers improved exhaust flow and enhanced engine responsiveness under extreme conditions.
With a precision-machined 1.595-inch valve head diameter and a bead lock groove design, these exhaust valves ensure stable valve retention and optimized gas evacuation, contributing to increased power and longevity of your Chrysler HEMI 6.1L engine.
Manley Performance Race Master Exhaust Valves incorporate advanced engineering and premium materials to support high-performance Chrysler HEMI 6.1L engines:
These exhaust valves are manufactured with meticulous attention to detail, utilizing premium-grade materials selected for their strength and thermal resistance. The bead lock groove is a critical design feature that securely holds the valve spring retainer in place, ensuring valve stability during aggressive camshaft events and sustained high RPM operation.
The 1.595-inch valve head diameter is carefully engineered to balance optimal exhaust flow with precise valve train geometry, promoting efficient combustion and exhaust evacuation. Manley’s precision machining guarantees tight tolerances for consistent fitment and dependable performance in demanding racing conditions.
The Manley Race Master Exhaust Valve Set is designed as a direct replacement for Chrysler 6.1L HEMI engines from 2005 to 2010, including the 300C, Dodge Challenger, Charger, Magnum, and Jeep Grand Cherokee SRT8 models. Installation requires standard engine assembly procedures and proper valve spring selection compatible with the bead lock groove design.
No special modifications such as cutting, drilling, or tuning are necessary, making this valve set a straightforward upgrade for performance builds focused on durability and high RPM capability.
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!
