Ferrea Nissan VG30D/VG30DTT Dual Valve Spring - Set of 24

This set includes 24 Ferrea dual valve springs, specifically made for Nissan VG30D and VG30DTT engines. These springs are crucial for keeping your engine's valvetrain in sync, especially when you're pushing the engine hard or making modifications. They ensure that the valves close quickly and reliably, preventing issues like valve float at higher RPMs, which can lead to serious engine damage.

Ferrea is known for making well-built valvetrain components, and these springs are no exception. They are constructed from high-strength spring steel, chosen for its ability to withstand the constant stress and heat cycles inside an engine. The dual spring design offers increased seat pressure and a higher open pressure compared to single springs, which is important for maintaining valve control with aggressive camshafts or forced induction setups common on the VG30DTT. This setup helps ensure your engine performs consistently and reliably, even under demanding conditions.

When installing these, it's important to follow the manufacturer's specifications for seat pressure and installed height to get the most out of them and ensure proper valvetrain geometry. This set is designed to be a direct replacement for the factory springs, but it's always a good idea to check your camshaft specifications to ensure they are compatible with the spring's pressure ratings. Proper installation is key to achieving the improved performance and reliability these springs offer.
