What is the purpose of single valve springs in a performance engine?

Single valve springs are often used in performance applications to provide adequate spring pressure for aftermarket camshafts. They help ensure the valves close quickly and completely, preventing valve float at higher engine speeds.

How many springs are included in this set?

This set contains 16 single valve springs, which is the correct quantity for a complete engine build on a 4-cylinder engine like the Toyota 4AG.

What should I consider before installing these valve springs?

Before installation, it's important to consult your engine's service manual for the proper procedure. Ensure you have the necessary tools for valvetrain work, such as a valve spring compressor, and that you follow all recommended steps for a successful installation.

Product Details

Ferrea is known for making well-built valvetrain components, and this set of single valve springs for the Toyota 4AG engine is no exception. If you're rebuilding the top end of your 4AG, these springs are designed to handle the demands of performance camshafts and higher RPMs.

This set includes 16 individual springs, enough for a complete engine. They are constructed from strong materials to ensure consistent valve control, which is crucial for reliable engine operation, especially when you're pushing the limits. Proper valve spring tension helps prevent valve float, ensuring your valves close securely and on time, even at high engine speeds.

When installing these, make sure to refer to your engine's service manual for the correct procedure and any specific requirements for your 4AG model. Having the right tools and following the manual will ensure a smooth installation and optimal performance from your new valvetrain components.
