About this part

Product Details

Made from titanium, these Manley valve lock keepers are designed for an 8-degree lock angle and a .2754-inch valve stem. They are specifically intended for use with Manley's PRO 900 series valves, ensuring a precise fit and reliable performance in your engine's valvetrain.

Titanium is chosen for its strength-to-weight ratio, meaning these keepers are strong enough to handle the forces within the engine without adding unnecessary mass. This can contribute to improved valvetrain stability, especially at higher RPMs. The 8-degree lock angle is a specific design choice that works with compatible valve locks to create a secure seating surface, preventing the valve from dislodging under stress.

When rebuilding or upgrading your engine's valvetrain, using components designed to work together is key. These Manley keepers are part of a system built for performance, ensuring that your valves stay properly seated and your engine runs smoothly.
