What is the spring rate of this valve spring?

This Ferrea dual valve spring has a spring rate of 380 pounds per inch. This is a higher rate than stock, suitable for performance engine builds.

What does a dual valve spring do?

Dual valve springs use two concentric springs working together. This design provides better stability and control for the valves, especially at higher engine speeds and with more aggressive camshafts.

How many valve springs do I need to order for my engine?

This product is sold individually. You will need to order a quantity of 12 for a 6-cylinder engine like the 2JZ, as each cylinder has two intake and two exhaust valves, requiring two springs per valve.

About this part

Product Details

This is a single Ferrea dual valve spring designed for Toyota 2JZGE and 2JZGTE engines. It offers a spring rate of 380 pounds per inch, which is a notable increase over stock springs. This type of upgrade is commonly used when building or modifying engines for higher performance, allowing for more aggressive camshaft profiles and higher RPM limits without valve float.

Ferrea is known for making well-built valvetrain components. These springs are made to handle the increased stress and demands of performance applications. The dual spring design offers better stability and control over the valve at high engine speeds. This specific spring is sold individually, so you'll need to order the correct quantity for your engine build.
