Ferrea Ford Zetec ZX3 Dual Valve Spring - Single (Drop Ship Only)

Ferrea is known for making well-built valvetrain components, and this single dual valve spring is no exception. This part, the S10041-1, is specifically designed for the Ford Zetec ZX3 engine. It's a key piece for anyone rebuilding or modifying the top end of their engine, ensuring the valves close properly under demanding conditions.

This is a single dual valve spring, meaning it's one half of a set of dual springs. Dual springs are often used in performance applications to provide better control over valve motion, especially at higher RPMs. They help prevent valve float, which is when the valve train can't keep up with the camshaft's speed and the valve doesn't close fully. Ferrea uses strong materials and precise manufacturing to create springs that can handle the stress of repeated opening and closing.

Because this is a single spring, you'll need to purchase the correct quantity for your specific engine build. Always refer to your engine's service manual or your performance build guide to determine the exact number of springs required per cylinder. This part is drop-shipped directly from the manufacturer.
