What material are these valve spring retainers made from?

These Manley Performance valve spring retainers are made from a high-strength Ti-17 Titanium material. This titanium alloy is chosen for its excellent strength-to-weight ratio, which helps reduce valvetrain mass.

What type of valve locks do I need to use with these retainers?

These specific Manley retainers are designed to be used with 7-degree valve locks. It's important to use the correct type of valve lock to ensure proper function and retention of the valve spring.

What is the benefit of using titanium retainers?

Using titanium retainers like these significantly reduces the overall mass in the valvetrain. This reduction in weight can help improve the engine's ability to reach higher RPMs and ensures more stable valve control at speed.

About this part

Product Details

When you're building or rebuilding an engine, especially one that's going to see high RPMs, the details matter. These Manley Performance Titanium Valve Spring Retainers are a prime example. They're designed to work with 11/32-inch and 3/8-inch valve stems and are specifically made for use with 7-degree valve locks. They play a crucial role in keeping your valvetrain stable, especially as the engine speed climbs.

Manley uses their high-strength Ti-17 Titanium material for these retainers. This isn't just about making them look good; titanium is significantly lighter than steel, and reducing mass in the valvetrain is key to improving RPM potential and ensuring the valves close reliably. They've CAD designed these retainers to shave off as much weight as possible without compromising their strength. Each retainer weighs in at just 15.0 grams, and they're designed to be installed at an additional 0.100 inches of height compared to stock, allowing for specific spring setups. These are made to precise tolerances to ensure they fit right and perform as expected under stress.

If you're aiming for maximum performance and reliability in a high-revving engine build, these retainers are a solid choice. They are intended for use with double valve springs that have a 1.500-inch diameter. Remember, these are designed to work with 7-degree valve locks, so make sure you have those on hand for installation.
