What is the purpose of a valve spring retainer?

A valve spring retainer holds the valve spring in place at the top of the valve stem. It works with the valve spring to ensure the valve closes properly and quickly, which is crucial for engine performance.

What material are these retainers made from?

These retainers are precision machined from high-grade SAE 4140 chromemoly steel. They are then finished with a black oxide coating for added durability and corrosion resistance.

Do these retainers come with valve locks (keepers)?

This product listing is for the retainers only. The valve locks, also known as keepers, are sold separately and are required to secure the retainer to the valve stem.

Product Details

When you're rebuilding the top end of your engine and using valve springs with larger diameters, you need retainers that can handle the increased pressure. COMP Cams Steel Retainers are built for this job. They are designed to work with valve springs ranging from 1.437 inches to 1.500 inches in diameter.

Engineers used advanced computer modeling, including 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 valve lift. Each retainer is precisely machined using CNC equipment from high-grade SAE 4140 chromemoly steel, ensuring they are well-built and durable for demanding applications. The black oxide finish adds a layer of corrosion resistance.

This set includes 16 retainers, suitable for a wide range of Chrysler and Dodge vehicles from the 1960s through the 1990s, like the Dodge D150 or Chrysler Newport. They feature a 10-degree lock angle, which is a common specification for many performance valve spring setups.
