Product Details

When you're pushing your Nissan VQ35DE or VQ35DET engine to its limits, especially with aggressive aftermarket camshafts, the stock valve springs might not keep up. This Manley Performance Valve Spring and Retainer Kit is designed to give you the valvetrain stability needed for high-RPM operation, up to 10,000 RPM.

This kit includes 24 matched valve springs made from a chrome-silicon alloy. This material offers excellent fatigue resistance and high tensile strength, which means consistent valve control even under extreme stress. The kit also features aerospace-grade titanium retainers, which are CNC machined to very precise tolerances. Titanium is chosen here for its strength and light weight, helping to reduce valvetrain mass. Keep in mind that this specific part number does not include valve locks, so you'll need to source those separately.

This kit is a popular choice for builds targeting high performance and racing applications, offering a well-built solution for demanding valvetrain needs. It fits a wide range of Nissan and Infiniti vehicles, including models like the 350Z, Altima, Maxima, and Infiniti G35. Ensure you have the correct valve locks for your application before installation.
