Why choose titanium retainers over steel for my VQ35DET?

Titanium retainers are significantly lighter than their steel counterparts. This reduced mass helps the valve spring control the valve more effectively, especially at higher engine speeds, which can prevent valve float and improve overall engine response.

What does 'Prop 65' mean for this part?

California's Proposition 65 requires businesses to provide warnings about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. This warning indicates the presence of such chemicals, though it does not necessarily mean the product is unsafe when used as intended.

Do these retainers come with new valve springs?

This product includes 24 titanium retainers only. Valve springs are sold separately, and you will need to select compatible springs based on your specific engine build requirements.

Product Details

Made from strong titanium, these Manley valve spring retainers are a smart choice for anyone rebuilding or modifying their Nissan VQ35DET engine. They’re designed to handle the increased stress and higher engine speeds that come with performance builds, helping to keep your valve train stable when you’re pushing the engine hard. Titanium is chosen here because it’s significantly lighter than steel, which reduces the overall mass the valve spring has to control. This improved control means better valve seating and less chance of valve float at high RPMs.

This set includes 24 pieces, enough for a full engine build on popular VQ35DET applications like the Infiniti FX35, G35, and Nissan 350Z. When you’re working on an engine that’s going to see a lot of action, using well-built components like these retainers makes a real difference in reliability and performance. They fit right into the factory valve spring setup, making them a straightforward upgrade during an engine overhaul.
