What is the main benefit of using Tool Steel retainers?

Tool Steel retainers offer a combination of light weight and exceptional strength and wear characteristics. This helps reduce valvetrain mass, which can improve performance and durability, especially in high-RPM applications.

Are these retainers suitable for stock engines?

While these retainers are built for demanding race applications, their lightweight and strong construction can also benefit performance-oriented street engines. They are designed to work with specific valve spring diameters and angles, so ensure compatibility with your existing or planned valve train components.

What is the 10-degree angle referring to?

The 10-degree angle refers to the taper on the retainer where it interfaces with the valve spring. This specific angle is designed to ensure a secure and proper fit with compatible valve springs, contributing to the overall stability of the valve train.

Product Details

If you're rebuilding the top end of your engine and looking for improved valve train performance, these Tool Steel Retainers from COMP Cams are a solid option. They are designed to work with valve springs that have an outer diameter between 1.500 and 1.550 inches and feature a 10-degree angle to fit all stem sizes. These retainers are a key component in ensuring your valve train operates smoothly and reliably, especially under high RPM conditions.

What sets these retainers apart is their construction from high-grade Tool Steel. This material offers a great balance of light weight, exceptional strength, and wear resistance. They are approximately 33% lighter than traditional chromemoly steel retainers, which helps reduce overall valvetrain mass. This reduction in mass can lead to improved performance and durability. COMP Cams developed these retainers using advanced CAD and FEA software, and they are CNC-machined for consistent quality, then Spintron-tested to ensure they can handle extreme RPMs. This makes them suitable for demanding race applications as well as performance street builds.

This set includes 16 retainers, enough for a typical V8 engine. They fit a wide range of Ford and Mercury vehicles from the 1970s and early 1980s, such as the Ford F-150, Mercury Cougar, and Ford Gran Torino. Make sure to check the full fitment list to confirm compatibility with your specific vehicle.
