What material are these COMP Cams retainers made from?

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

What is the purpose of the contoured top profiling on these retainers?

The contoured top profiling, developed using advanced CAD and FEA analysis, is designed to lower stress on the retainer and reduce its overall mass. This also contributes to allowing for increased valve lift.

Do these retainers come with the valve keepers?

This product listing is for the steel retainers only. They are designed to work with 10-degree superlock keepers, which are sold separately.

Product Details

What you get in this box is a set of 12 COMP Cams Steel Retainers, specifically designed for valve springs with diameters between 1.437 and 1.500 inches. These are essential when you're upgrading to valve springs that create higher pressures, ensuring everything stays securely in place under demanding conditions. They are built from high-grade SAE 4140 chromemoly steel, a strong material chosen for its durability.

COMP Cams used advanced 3D CAD and FEA analysis to shape these retainers. This process resulted in a contoured top profiling that helps reduce stress and mass, while also allowing for increased valve lift. Each retainer is CNC-machined to very precise tolerances, meaning they fit right and work reliably with your valve train components. This attention to detail is key for consistent performance, especially in engines that see a lot of use.

These retainers are a solid option for a wide range of vehicles, from classic Chevrolet models like the Bel Air and Camaro to more modern trucks and vans such as the Chevrolet Astro and Express. They are designed to work with 10-degree superlock keepers.
