Supertech Nissan SR20DET 6mm Valve Stem Inner Spring Seat Locator - Single (Drop Ship Only)

Supertech is known for making well-built valvetrain components, and this inner spring seat locator for the Nissan SR20DET engine is no exception. This part is designed to sit precisely where the valve spring rests, ensuring it's properly supported and centered. It's a small but critical piece for anyone rebuilding or modifying their SR20DET cylinder head.

This specific locator is made for 6mm valve stems, which is common for the SR20DET. It's a single piece, so you'll need to order one for each valve. Getting these seats right is important for consistent spring pressure and to prevent the spring from walking, which can lead to all sorts of valvetrain issues. It's a straightforward part to install when you're already working on the cylinder head, fitting right into place to do its job.
