What is included in this set of Manley titanium valves?

This set includes eight Manley Performance titanium intake valves. Each valve has a 2.400-inch head diameter and a 0.3415-inch stem diameter. It is important to note that tip protection hardware is sold separately.

Why is tip protection required for these valves?

These Manley titanium valves do not come with a hardened tip from the factory. To prevent wear and ensure longevity in high-RPM applications, you must use a compatible wear cap, such as Manley part numbers 42104, 42104TM, or the Manley LocCap System.

What are the benefits of using titanium valves?

Titanium valves are significantly lighter than traditional steel valves. This reduction in valve train mass allows for higher engine speeds, improved efficiency, and better compatibility with aggressive camshaft profiles, making them ideal for performance-oriented builds.

About this part

Product Details

This set includes eight Manley Performance titanium intake valves, each featuring a 2.400-inch head diameter and a 0.3415-inch stem diameter. These valves are crafted from exceptional titanium alloys, chosen for their balance of mechanical properties, hardness, ductility, and fatigue strength at elevated temperatures. They are designed to significantly reduce valve train weight, which is crucial for improving engine efficiency and enabling higher engine speeds, especially in applications that spend a lot of time at high RPMs or utilize aggressive camshaft profiles.

Manley constructs these valves from a single piece of forged titanium, incorporating grain flow for enhanced durability and to minimize potential weak points. They are then meticulously machined in advanced CNC turning centers and valve stem grinders to hold very precise tolerances. The 'B' suffix in the part number indicates that these valves feature Manley's Bead Loc? single radius keeper groove. It's important to note that these valves do not come with a hardened tip, so tip protection is required. You'll need to use a Manley wear cap, such as part numbers 42104, 42104TM, or the Manley LocCap System, to protect the valve tip during operation.

Each valve undergoes a rigorous final inspection to ensure uncompromising quality and reliability. The tight tolerances achieved during manufacturing mean you get a product that meets the highest precision standards, essential for optimal valve performance in demanding engine builds.
