Ferrea Nissan SR20DE/SR20DET Dual Valve Spring - Single (Drop Ship Only)

Ferrea's S10038-1 dual valve spring is built from high-strength steel, a material chosen for its ability to handle the stresses of high-RPM engine operation. This spring is specifically designed for Nissan SR20DE and SR20DET engines, which are known for their performance potential. When you're rebuilding the top end or looking to upgrade your engine's valvetrain, a well-built spring is crucial for keeping your valves closing reliably at speed.

This single spring is part of a system designed to work together to control valve motion. The dual spring design offers increased seat pressure and a higher open pressure compared to single springs, which helps prevent valve float, especially in modified engines that see higher boost or RPMs. Ferrea is a well-known name in performance valvetrain components, and this spring reflects their focus on durability and performance for these popular Nissan engines.

When installing new valve springs, it's always a good idea to inspect your valve seals and retainers as well. Ensure you have the correct tools for compressing the springs during installation to avoid damaging other engine components.
