Manley Performance Race Master Exhaust Valves are precision-engineered for Chevrolet 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 offer exceptional durability and reliability for high-performance applications. Whether you are building a high-revving race motor or upgrading your factory valvetrain, Manley’s Race Master valves provide the strength and consistency needed to maintain optimal engine performance up to 8000 RPM.
These exhaust valves are an ideal upgrade for racers and performance enthusiasts seeking enhanced valvetrain longevity and efficiency under extreme operating conditions. Their robust construction and precise fitment ensure dependable operation in demanding environments.
Manley Race Master Exhaust Valves combine advanced materials and design innovations to deliver superior performance and durability. Key features include:
Manley Race Master Exhaust Valves are crafted from premium materials selected for their ability to endure the extreme temperatures and stresses encountered in high-performance exhaust systems. The triple groove stem design significantly improves valve guide retention, reducing valve wobble and premature wear during aggressive engine operation.
Each valve is precision-machined to tight tolerances, ensuring excellent sealing against the valve seat and smooth movement within the valve guide. This meticulous engineering contributes to improved combustion efficiency, consistent power delivery, and enhanced engine reliability on the track.
These exhaust valves are designed as direct replacements for stock valves in Chevrolet 5.7L HEMI engines produced from 2003 to 2008. They fit seamlessly using factory valve guides and seats without requiring any modifications, cutting, drilling, or special tuning. Compatible with both stock valvetrain components and aftermarket performance upgrades, installation is straightforward during engine rebuilds or valvetrain enhancements.
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!
