Ferrea Ford EcoBoost 3.5L Single Spring 7 Deg Pro CNC Titanium Retainer - Set of 24

This set includes 24 Ferrea single valve springs, each paired with a Pro CNC machined titanium retainer designed for a 7-degree lock. These components are specifically made for Ford EcoBoost 3.5L engines, addressing the critical need for reliable valve train operation under demanding conditions.

When you're pushing your EcoBoost 3.5L engine, especially if you've made modifications that increase airflow or boost pressure, the stock valve springs can become a limiting factor. They might not be able to keep up with higher RPMs or the increased cylinder pressures, leading to valve float or even valve-to-piston contact. Ferrea's single springs are engineered to provide the necessary seat and open pressures to keep your valves under control. The use of titanium for the retainers significantly reduces weight compared to steel, which lowers the overall mass the valvetrain has to move. This reduction in reciprocating mass can lead to improved engine response and allows the engine to rev more freely and safely. The Pro CNC machining ensures precise dimensions and a smooth finish, contributing to consistent performance and durability.

This set is designed as a direct replacement for the factory valve springs and retainers in your Ford EcoBoost 3.5L. Proper installation is key to achieving the performance benefits and ensuring the longevity of your engine. Always refer to the manufacturer's installation instructions for specific details regarding spring installation, retainer seating, and any required valvetrain adjustments. This upgrade is a solid choice for EcoBoost owners looking to enhance their engine's performance and reliability, particularly for those planning on tuning or more aggressive driving.
