What is the primary function of a single valve spring like this?

A single valve spring's main job is to close the engine's intake and exhaust valves quickly and reliably after they have been opened by the camshaft. This Ferrea spring is designed to maintain consistent pressure, which is crucial for preventing valve float, especially at higher engine speeds.

What does 'Drop Ship Only' mean for this product?

'Drop Ship Only' means the item ships directly from the manufacturer or a third-party warehouse to you, rather than from our main Auto Barn warehouse. This can sometimes affect delivery times.

Are these springs suitable for stock 4AGELU 20V engines?

These springs are designed for the Toyota 4AGELU 20V engine and are built to handle increased demands. While they can be used in stock applications, they are particularly beneficial if you plan on increasing engine RPMs or making other performance modifications to the valvetrain.

About this part

Product Details

The S10150-1 single valve spring from Ferrea is built for the Toyota 4AGELU 20V engine. This spring is designed to handle the demands of higher RPM operation, ensuring your valves close reliably when you're pushing the engine hard. Ferrea is known for making well-built valvetrain components, and these springs are no exception.

Constructed from high-tensile wire, this spring offers consistent pressure throughout its lifespan. It's a single spring design, meaning it's intended to replace the stock single spring setup. Proper spring function is critical for preventing valve float, which can lead to serious engine damage at high RPMs. This Ferrea spring helps maintain that crucial control.

When rebuilding or upgrading the valvetrain on your 4AGELU 20V, choosing reliable components like these Ferrea springs is key to achieving optimal performance and durability. Make sure to check the manufacturer's specifications for correct installation and any associated hardware you might need.
