What type of valve locks are needed for these Manley retainers?

These Manley spring retainers require 7-degree valve locks. You can use Manley's P/N 13098 or factory Chevrolet LS valve locks for proper fitment and performance.

What is the main benefit of using titanium retainers?

Titanium retainers are significantly lighter than steel ones. This reduced mass in the valvetrain helps the engine achieve higher RPMs more easily and reliably, especially in performance applications.

What does the '+.050" install height' specification mean?

The '+.050" install height' refers to the specific measurement from the valve seat to the retainer when the valve spring is installed. This ensures the correct spring pressure is achieved for optimal engine performance.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for performance applications, you'll want to pay close attention to the valvetrain. Manley's RET-TI 1.430 7 DEG +.050 spring retainers are made from special 6AL-4V titanium, which is known for being incredibly strong while also being very light. This is a big deal because reducing the weight of the parts that move up and down rapidly, like these retainers, helps the engine rev higher and more reliably.

These retainers are CAD designed to cut down on mass without giving up any strength, which is crucial when you're pushing an engine hard. They're CNC machined to tight specs, ensuring they work right with your valve springs and locks. Keep in mind you'll need to use 7-degree valve locks with these, and Manley recommends their own P/N 13098 or factory Chevrolet LS valve locks to get the best performance and ensure everything fits correctly. The +.050 inch install height is a specific measurement to ensure proper spring pressure.

At 14.0 grams each, these titanium retainers are a smart choice for anyone looking to improve their engine's high-RPM capabilities. They're a well-built component that can make a notable difference in how your engine performs when you really get on it.
