Ferrea Endurance High Lift Single Beehive Ovate PAC Alloy Valve Spring - Set of 16

Ferrea is well-known for making high-performance valvetrain components, and this set of Single Beehive Ovate PAC Alloy Valve Springs is a prime example of their work. These springs are designed for high-lift camshafts, meaning they can handle the increased lift and duration that performance camshafts require without losing their ability to close the valves quickly and reliably. If you're building a performance engine or upgrading your existing valvetrain for more aggressive cams, these springs are a solid choice.

What sets these springs apart is the PAC Alloy material they're made from. This advanced alloy offers excellent strength and fatigue resistance, which is crucial for springs that are constantly working under high stress. The beehive shape is also a notable design feature; it allows for a smaller retainer diameter, which reduces mass in the valvetrain. Less rotating mass means the engine can rev more freely and the valvetrain is more stable at high RPMs. The ovate wire shape further contributes to improved performance and durability by ensuring consistent spring performance under extreme conditions.

This set includes 16 springs, enough for a typical V8 engine. When installing high-lift springs like these, it's always a good idea to consult your camshaft manufacturer's specifications to ensure these springs are the correct rate and seat pressure for your specific application. Proper installation is key to unlocking their full potential and ensuring the longevity of your engine's valvetrain.
