What material are these valve springs made from?

These valve springs are constructed from PAC Alloy. This material is selected for its ability to withstand the high stresses and temperatures found in performance engine applications.

What is the spring rate of these Ferrea valve springs?

Each spring in this set has a rate of 191 pounds per inch. This specification is important for controlling valve motion, especially with performance camshafts.

What is the advantage of the beehive ovate design?

The beehive ovate design helps to reduce the overall mass of the valve spring. This can contribute to better valve control at higher engine speeds and reduce the potential for valve float.

About this part

Product Details

Ferrea is well-known for making high-performance valvetrain 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 or looking to upgrade your valvetrain for improved performance, these springs are designed to handle the demands of modified engines.

Each spring in this set is crafted from PAC Alloy, a material chosen for its strength and durability under high stress. They feature a beehive ovate design, which helps reduce mass and allows for higher RPMs compared to traditional cylindrical springs. With a spring rate of 191 lbs per inch, these springs offer a solid option for maintaining proper valve control, especially when using more aggressive camshafts. This set includes 16 springs, enough for a complete engine.
