What is a valve spring?

A valve spring is a critical component in your engine's valvetrain. Its job is to close the engine's intake and exhaust valves quickly and securely after they have been opened by the camshaft. This ensures proper sealing of the combustion chamber.

Why would I need a special alloy valve spring?

Special alloy valve springs are often used in performance applications or when rebuilding an engine. They are designed to handle higher RPMs and more aggressive camshaft profiles than stock springs, offering improved durability and consistent tension.

Do I need to buy multiple springs?

Yes, this part number is for a single valve spring. Your engine has many valves, so you will need to purchase the correct quantity to replace all the springs on your 1GR-FE engine.

About this part

Product Details

This is a single valve spring from Ferrea, designed for the Toyota 1GR-FE engine. Ferrea is known for making well-built valvetrain components, and these springs are made from a special alloy to handle the demands of performance or rebuilt engines.

When you're rebuilding the top end of your 1GR-FE, or if you're looking to upgrade to handle more aggressive camshafts, a strong valve spring is crucial. This spring is made from a special alloy that Ferrea uses, which is designed to maintain its tension and resist fatigue over time, even under high RPMs. It's a single spring, meaning it's one part of a set you'd need to replace all the valves.
