Good To Know

Q: How many retainers do I need for one engine? A: A full valvetrain service typically uses one retainer per valve, so order according to the number of valves you are servicing on your 1503 engine.

Q: Does this come as a single retainer or a set? A: Confirm the listing quantity before ordering, since retainers are often sold individually and a complete top-end job may require several.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
