Supertech Honda D16Z Valve Spring Seat Locator - Set of 8

These valve spring seat locators from Supertech are made from hardened steel, a strong material that resists wear and deformation under the stress of engine operation. They are designed to sit between the valve spring and the cylinder head, ensuring the spring is properly seated and centered. This is crucial for consistent valve spring performance and to prevent the spring from damaging the cylinder head surface over time.

Each set includes eight locators, enough for a complete D16Z engine. The hardened steel construction means these parts can handle the heat and pressure found in the combustion chamber, contributing to the overall reliability of your valve train. Proper seating of the valve springs helps maintain the correct spring tension, which is important for preventing valve float at higher RPMs.
