What material are these valve springs made from?

These valve springs are constructed from PAC Alloy. This material is selected for its strength and its ability to maintain consistent tension over time, which is crucial for engine performance.

What is the spring rate of these springs?

The spring rate for this set of Ferrea valve springs is 275 pounds per inch. This rate helps ensure the valves close reliably, even at higher engine speeds.

What is the advantage of the beehive and ovate wire design?

The beehive shape and ovate wire design help to reduce the overall mass of the valve spring. This reduction in mass is beneficial for allowing the engine to achieve higher RPMs more safely and efficiently.

About this part

Product Details

Ferrea is well-known for making high-performance engine components, and this set of single beehive valve springs for Ford 4.6L 16V engines is a prime example. If you're rebuilding the top end of your 4.6L engine and need reliable valve springs, this set is built to handle the demands of performance applications.

These springs are made from PAC Alloy, a strong material chosen for its durability and ability to maintain consistent tension. They feature an ovate wire design and a beehive shape, which helps reduce mass and allows for higher RPMs compared to traditional dual springs. With a spring rate of 275 lbs per inch, they offer a solid tension that helps keep your valves seated properly, even under aggressive driving conditions. This set includes 16 springs, enough for a complete V8 engine.
