What is the main benefit of using titanium valves?

Titanium valves are significantly lighter than traditional steel valves. This weight reduction helps improve engine efficiency, allows for higher RPM operation, and can reduce stress on the valve train components.

Do these valves come with hardened tips?

No, these Manley titanium valves do not come with a hardened tip. You will need to install a wear cap, such as Manley's P/N 42104, 42104TM, or the Manley LocCap System, for tip protection.

What kind of construction do these valves feature?

These valves are made with a one-piece forged construction. This method ensures consistent grain flow throughout the valve, creating a more durable part compared to designs that use welding.

About this part

Product Details

If you're building a high-performance engine that needs to spin fast and reliably, Manley's Titanium Exhaust Valves are a serious consideration. These aren't your average valves; they're crafted from special titanium alloys to significantly cut down on weight in your valve train. This reduction is key for improving overall engine efficiency and allowing your engine to handle higher RPMs safely, especially when paired with aggressive camshafts.

What sets these valves apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding the potential weak spots found in welded designs. Manley machines these valves with advanced CNC equipment to exacting tolerances, ensuring they perform precisely as they should. The titanium alloys used are chosen for a good balance of strength, hardness, and ductility, even at the high temperatures found in an engine. Each valve is thoroughly inspected to meet strict quality standards.

It's important to note that these valves do not come with a hardened tip and require tip protection. Manley recommends using their wear cap P/N 42104, 42104TM, or the Manley LocCap System to prevent wear. This set includes eight exhaust valves, each measuring 2.000 inches in diameter with a 0.3415-inch stem and an overall length of 5.020 inches.
