What is the purpose of a valve spring retainer?

A valve spring retainer holds the valve spring compressed against the cylinder head. It's crucial for keeping the valve train properly tensioned and ensuring the valve closes securely after the camshaft lobe passes.

What does the '11 degree' refer to on these retainers?

The '11 degree' refers to the lock angle of the retainer groove, which mates with the valve keeper. This specific angle is designed to work with the valve keepers and the valve spring's intended operation for optimal performance.

Are these retainers suitable for stock engines or only performance builds?

While these retainers are well-built and feature advanced design elements for performance, they are designed to work with specific valve spring diameters. They are a solid option for both stock replacements and performance engine builds where upgraded valve springs are used.

Product Details

When you're upgrading your engine's valve springs, especially with larger diameter springs that create higher pressures, you need retainers that can handle the load. These COMP Cams Steel Retainers are built from high-grade SAE 4140 chromemoly steel, a strong material chosen for its durability under stress. They are CNC-machined to precise tolerances, ensuring a solid fit with your valve springs and stems.

COMP engineers used advanced 3D CAD and FEA analysis to develop a contoured top profiling. This design helps reduce stress on the retainer, allows for increased valve lift, and also cuts down on overall mass. The 11-degree lock angle is designed to work with specific valve spring diameters, fitting springs from 1.225 inches to 1.250 inches. These retainers are black oxided for added protection and are a well-built choice for performance engine builds.

These retainers are designed to fit a wide range of V8 engines, including popular models like the Buick 350 and 455, Chevrolet Chevelle, and GMC C1500 Pickup. Always double-check the fitment data to confirm compatibility with your specific vehicle.
