What material are these retainers made from?

These retainers are CNC-machined from high-grade SAE 4140 chromemoly steel. This is a strong and durable material chosen for its performance in demanding engine applications.

Are these retainers compatible with all valve springs?

These retainers are specifically designed to work with larger diameter valve springs that develop higher pressures. They are intended for use with stock valve stem sizes and stock spring diameters.

What is the benefit of the contoured top profiling?

The advanced contoured top profiling, developed using 3D CAD and FEA, helps to lower stress on the retainer and reduce its overall mass. This contributes to increased valve lift capability for your engine.

Product Details

If you're upgrading your Ford 3.8L or 4.2L engine's valve springs, you'll need retainers that can handle the increased pressure. These steel retainers from COMP Cams are built to do just that. They are designed to work with larger diameter valve springs, ensuring your valve train stays stable under higher loads.

COMP Cams used advanced 3D CAD and FEA analysis to shape these retainers. This process resulted in a contoured top profile that reduces stress and mass, while also allowing for increased lift. Each retainer is CNC-machined to precise specifications from high-grade SAE 4140 chromemoly steel, a strong material known for its durability. This means they fit right and perform reliably, supporting your engine's performance upgrades.

These retainers are a solid option for a wide range of Ford, Lincoln, and Mercury vehicles from the late 80s through the mid-2000s, including popular models like the Ford Mustang, F-150, and Windstar. They are designed for stock valve stem sizes and stock spring diameters, making them a straightforward component for your valve train build.
