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 maintaining proper valve operation, especially when using higher-pressure valve springs that require a stronger retainer.

What does the 10-degree lock angle mean?

The 10-degree lock angle refers to the angle of the groove where the valve stem lock (keeper) sits. This is a common angle used in many performance engine builds and ensures a secure fit for the valve stem locks.

Are these retainers suitable for all valve springs?

No, these retainers are specifically designed for valve springs with an outside diameter ranging from 1.500 inches to 1.550 inches. It's important to match the retainer size to your valve spring diameter for proper function.

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 built from SAE 4140 chromemoly steel, a strong material chosen for its durability under high stress. They're CNC-machined using CAD/Cam software to precise tolerances, ensuring a solid fit with your valve springs. The contoured top profiling, developed with 3D CAD and FEA analysis, helps reduce stress and mass while allowing for increased lift.

These retainers are specifically designed for valve springs with an outside diameter between 1.500 inches and 1.550 inches, like COMP's popular 911, 932, 26115, and 935 series springs. They feature a 10-degree lock angle, which is a common setup for many performance applications. The black oxide finish adds a layer of corrosion resistance and gives them a clean look. This set includes 16 retainers, enough for a complete V8 engine.

This part fits a wide range of vehicles, including many Chevrolet models like the C10 Pickup, Camaro, and Corvette, as well as numerous other makes and models. Always check the full fitment guide to confirm compatibility with your specific vehicle.
