GM 1960325 — Valve Stem Seal (Umbrella‑Type)

Group 0.308 — Valve Stem Oil Control

GM 1960325 is a single valve‑stem oil seal, used widely across Chevrolet engines in the 1960s and early 1970s. It is part of the same family as the boxed set you have (3856874), but 1960325 is the individual service seal, not the full kit.

This number appears in GM’s service catalogs as a replacement umbrella‑style valve seal for both small‑block and big‑block Chevrolet engines.
