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 control valve movement and prevent the spring from coming loose, especially under higher pressures from performance springs.

What does '10 Degree Superlock' mean for these retainers?

The '10 Degree Superlock' refers to the angle of the keeper groove on the valve stem. This specific angle is designed to work with matching 10-degree keepers, ensuring a secure lock between the retainer and the valve stem.

What material are these retainers made from and why is it important?

These retainers are made from SAE 4140 chromemoly steel. This is a strong and durable alloy that can withstand the significant forces and pressures exerted by performance valve springs, helping to prevent failure in demanding engine conditions.

Product Details

When you're upgrading your valve springs to handle more pressure, you need retainers that can keep up. These COMP Cams Steel Retainers are made from high-grade SAE 4140 chromemoly steel, a strong material that can withstand the increased forces. They are designed to work with valve springs that have a diameter between 1.437 inches and 1.500 inches, a common range for performance applications.

COMP Cams used advanced 3D CAD and FEA analysis to contour the top profiling of these retainers. This design choice helps reduce stress and mass while allowing for increased valve lift. Each retainer is CNC-machined to precise tolerances, ensuring they fit right and perform consistently. This set includes 12 retainers, suitable for most V8 engines.

These retainers fit a wide variety of Chrysler and Dodge vehicles from the 1960s through the 1980s, including models like the Dodge D150 pickup and the Chrysler New Yorker. If you're rebuilding or modifying your engine's top end, these retainers are a solid option to ensure your valve springs are properly supported.
