What is the primary benefit of upgrading to these Manley valve springs?

These Manley valve springs are designed to provide more reliable valve control, especially at higher engine speeds (RPMs). They help prevent valve float, which is when the valves don't close properly due to excessive spring pressure, ensuring better engine performance.

Do these valve springs come with retainers or other hardware?

This part number (22170-24) is for a 24-piece set of valve springs only. Retainers, seals, and other necessary hardware for installation are typically sold separately and should be confirmed based on your specific engine rebuild needs.

Are these springs suitable for a stock VQ35DET engine, or are they only for modified builds?

While these springs offer improved performance for modified engines or those intended for higher RPM use, they can also be used as a direct replacement for stock springs during a rebuild. They offer a well-built option that provides consistent pressure and durability.

Product Details

If you're working on a Nissan VQ35DET engine, these 24-piece valve springs from Manley Performance are a solid choice for rebuilding or upgrading your top end. They're designed to handle the demands of higher RPM operation, ensuring your valves close reliably when you're pushing the engine harder. This set fits a range of popular Nissan and Infiniti models, including the 350Z, Altima, Maxima, G35, and FX35.

Manley is known for making well-built internal engine components, and these valve springs are no exception. They're made from strong materials to resist fatigue and maintain consistent pressure over time. This improved valve control is crucial for preventing valve float, especially when you've modified the engine for more power or plan to rev it higher than stock. The springs are designed to work with the factory retainers and valve seals, making them a straightforward replacement during a cylinder head rebuild.

When you're rebuilding the cylinder heads on your VQ35DET, using a matched set of valve springs like these ensures uniform performance across all cylinders. This helps your engine run smoother and more efficiently. Make sure to refer to your vehicle's service manual for the correct installation procedures and any specific tool requirements.
