Product Details

If you're upgrading your valve springs to handle more pressure, you'll need retainers that can keep up. These COMP Cams steel retainers are built to work with valve springs that have a larger diameter, like some of the popular COMP springs such as the 984 or 990. They're designed to manage the increased forces that come with higher spring pressures, which is crucial for engine performance and reliability.

COMP Cams used advanced computer modeling, including 3D CAD and FEA, to shape these retainers. This design process focused on reducing stress and mass while allowing for increased lift. They are precision CNC-machined from high-grade SAE 4140 chromemoly steel, ensuring they meet exact tolerances. The black oxide finish adds a layer of corrosion resistance and a clean look. This retainer is specifically made for 3/8-inch valve stems and works with valve springs in the 1.437-inch to 1.500-inch diameter range.

This part fits a wide range of vehicles, including many Chevrolet C/K series trucks from the 80s and 90s, as well as classic Mopar models like the Dodge D150 and Chrysler Cordoba. It's a solid option when you need dependable valve spring support for your engine build.
