What is the main benefit of using Viton valve stem seals?

Viton seals offer superior resistance to high temperatures and harsh engine oils compared to standard rubber seals. This durability helps them last longer and maintain a better seal over time, especially in demanding engine conditions.

What does the '5.5mm' refer to in the product name?

The '5.5mm' indicates the diameter of the valve stem that these seals are designed to fit. It's important to ensure this matches the valve stems on your specific engine for a proper seal.

Do these seals come with any installation hardware?

This product is a set of valve stem seals only. Installation hardware, such as valve keepers or retainers, is not included and should be sourced separately if needed for your engine rebuild.

Product Details

If you're rebuilding the top end of your Nissan VQ35DE engine, replacing the valve stem seals is a crucial step. These seals keep oil from leaking down the valve guides into the combustion chamber, preventing blue smoke on startup and oil consumption. This set from GSC Power Division uses Viton material, known for its excellent resistance to heat and oil, which is exactly what you need in this high-temperature environment.

This particular set is designed for a 5.5mm valve stem, a common size for many VQ35DE applications. Viton seals are a solid choice because they hold up better over time compared to standard rubber seals, especially in engines that see a lot of heat. Installing these seals is typically done during a cylinder head or valve job, so it's a good idea to have them on hand when you're already working on that part of the engine.

This set fits a wide range of Nissan and Infiniti vehicles, including popular models like the Altima, Maxima, and 350Z. Make sure to verify fitment for your specific year and model.
