About this part

Product Details

When you're rebuilding the top end of your Nissan Patrol engine, especially for racing applications, you need components that can handle the heat and stress. This set includes twelve Manley Race Master exhaust valves, each measuring 35mm. These are specifically designed for engines that will be operating under 8000 RPM, making them a solid choice for bracket, drag, and oval track racing.

You're getting valves built from high-quality stainless steel, which is known for its durability. The stems are chrome-plated, and they have hard tips, adding to their longevity and resistance to wear. Manley also swirl polishes the areas under the head and fully machines the combustion faces. This attention to detail helps optimize airflow into the cylinder and improves combustion efficiency, which is crucial for getting the most out of your engine. These Race Master valves feature a straight stem design, and they are recommended for use in alcohol-fueled engines, where they've shown reliable performance even under demanding conditions.
