Supertech Nissan VQ35DET Dual Valve Spring Kit

This is the Supertech Dual Valve Spring Kit for the Nissan VQ35DET engine. If you're building a performance VQ35DET, especially one that's going to see higher RPMs or be fitted with a more aggressive camshaft, upgrading your valve springs is a critical step. Stock springs can struggle to keep up when the engine is pushed beyond its original design limits, leading to valve float and potential engine damage. This kit gives you the well-built components needed to handle those increased demands.

Supertech uses high-tensile chrome-silicon wire for these springs, which is a standard material for performance valve springs because it offers excellent strength and durability. The dual spring design means you have an inner and outer spring working together. This setup helps to control valve motion more effectively across a wider RPM range and also provides a safety margin; if one spring were to fail, the other can often keep the valve seated, preventing catastrophic engine damage. This kit is designed to work with the specific geometry and requirements of the VQ35DET, ensuring proper fitment and function when you're rebuilding or modifying your engine's top end.

When installing this kit, it's important to have the correct tools for valve spring compression and replacement. You'll also want to ensure your camshafts are compatible with the increased spring pressure and lift capabilities this kit offers. This is a solid option for anyone serious about getting the most out of their VQ35DET build, providing the reliability and performance needed for demanding applications.
