What material are these spring retainers made from?

These Manley spring retainers are constructed from titanium. Titanium is chosen for its high strength-to-weight ratio, making these retainers significantly lighter than traditional steel versions.

What does the '+.050 LW' in the part name mean?

The '+.050 LW' designation indicates that these retainers are sized for a specific valve spring diameter, specifically 0.050 inches larger than a standard size, and are a lightweight (LW) version. This ensures proper fitment with compatible valve springs and contributes to reduced valvetrain mass.

Are these retainers suitable for stock engines?

While these retainers are designed for high-performance applications, they can be used in stock engines if you are upgrading your valve springs to a compatible set. Their primary benefit is reducing valvetrain mass, which is most impactful in performance builds.

About this part

Product Details

Manley Performance is well-known for making strong, reliable engine components for demanding applications. This particular part, the RET-TI SUPER 7 +.050 LW spring retainer, is a prime example of their commitment to performance. It's designed to work with valve springs, holding them securely in place under high stress. If you're building or rebuilding a performance engine where valve control is critical, these retainers are a solid choice.

What sets these retainers apart is their construction. They are made from titanium, which is significantly lighter than steel. This reduced mass at the valve train means less reciprocating weight, allowing your engine to rev more freely and potentially improving overall performance. The '+.050 LW' in the name indicates they are designed for a specific valve spring size and are a lightweight version, further contributing to reduced valvetrain mass. This attention to detail in material selection and design is what you expect from a company like Manley.

When you're working on a high-performance engine, every component matters. These Manley retainers are built to withstand the rigors of competition or aggressive street driving. They are a direct replacement for stock retainers in many applications, but offer a significant upgrade in terms of weight savings and durability under stress. Ensure you are using them with compatible valve springs and retainers for optimal performance and longevity.
