Good To Know

Q: Do I need to replace retainers when changing valve springs? A: Retainers are commonly replaced alongside springs and seals during a top-end refresh. Inspect the old retainers for wear or distortion before reuse.

Q: How many retainers does one engine need? A: A 1503 engine uses one retainer per valve, so order the quantity that matches your valve count. Confirm the exact count for your configuration before ordering.

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