VALVE SPRING SEAT SET SR SERIES 0.5mm 8pcs
SKU: T00F TA305A-NS08C
Easy — 1–2 hours
Description
These valve spring seats are used to adjust the load applied to each spring during aftermarket valve spring installation. They help achieve uniform spring specification, which is crucial for race engines to increase RPM without issues. By using various seat thicknesses, the same objective as the time-consuming and costly "blueprinting" method can be achieved at a fraction of the cost. Tomei Powered utilizes these seats in their race engines to ensure uniform specifications.
