What type of valve springs are these retainers designed for?

These Ferrea retainers are specifically designed to be used with double valve springs. Double springs are often chosen for performance engines that require higher spring pressures to prevent valve float at high engine speeds.

What makes Super 7 tool steel a good material for retainers?

Super 7 tool steel is chosen for its inherent strength and resistance to wear. This makes it well-suited to handle the repetitive stresses and forces within a high-performance engine's valve train.

How many retainers are included in this set?

This set includes 16 valve spring retainers. This quantity is typically sufficient for a V8 engine, which has 8 intake and 8 exhaust valves.

About this part

Product Details

If you're rebuilding the top end of a high-performance engine, you need valve spring retainers that can handle the stress. These Ferrea Double Spring Pro CNC Super 7 Tool Steel Retainers are built to keep your valve train stable under demanding conditions. They are designed to work with double valve springs, which are common in performance applications where higher spring pressures are needed to control valve float at high RPMs.

Ferrea uses Super 7 tool steel for these retainers, a material known for its strength and durability. The CNC machining ensures precise dimensions, which is critical for proper valve train geometry and function. This set includes 16 retainers, enough for a typical V8 engine. Their well-built nature means they can withstand the repeated forces from aggressive camshaft profiles and high engine speeds, helping to maintain consistent valve control.
