What is the spring rate of these Ferrea valve springs?

These Ferrea valve springs are rated at 380 lbs per inch. This specification indicates the force required to compress the spring by one inch, signifying their strength for performance applications.

Are these valve springs suitable for stock 2JZ engines?

While these springs are designed for 2JZGE and 2JZGTE engines, their 380 lbs/inch rating is intended for modified or high-performance applications. For a completely stock engine, a less aggressive spring might be considered, but these offer significant headroom for future upgrades.

What is the benefit of dual valve springs?

Dual valve springs offer improved dampening and stability compared to single springs. This design helps prevent valve float at higher engine speeds and under boost, ensuring more consistent valve operation and better engine performance.
