What does the '+.050' designation mean for these keepers?

The '+.050' indicates that these keepers are designed for valves that have been machined to have a stem diameter that is 0.050 inches larger than the standard size. This is common in performance engine builds where larger valves or different spring pressures are used.

What is the benefit of titanium for valve keepers?

Titanium is used because it offers a strong yet lightweight material. This helps reduce the overall mass in the valve train, which can improve stability and performance, especially at higher engine speeds.

What is the purpose of the special coating on these keepers?

The special coating on these Manley valve keepers is designed to reduce friction and wear where the keeper interfaces with the valve spring retainer. This can help extend the life of the components and maintain consistent valve train operation.

About this part

Product Details

These Manley valve lock keepers are made from titanium and are +.050 inch oversize, meaning they are designed to work with valves that have had their stems machined to be 0.050 inches larger than stock. The titanium material is chosen for its strength and light weight, which is important for valve train stability at high RPMs. They also feature a special coating that helps reduce wear and friction in the valve spring retainer groove.

When you're rebuilding an engine, especially one that's going to see a lot of action, the valve train components need to be up to the task. These keepers are a well-built part from Manley, a company known for its performance engine parts. The +.050 sizing indicates these are intended for modified engines where valve stem diameters have been changed to accommodate different valve sizes or spring pressures. Make sure to confirm your valve stem diameter before ordering.
