Product Overview
Cracked or missing plastic retainers are often discovered during valve-lash, injector, or rocker-arm service. These small clips keep the rocker socket located on the ball end and should not be ignored when they have become brittle.
This set supplies 12 retainers for a complete matched service. If a retainer has broken, inspect the rocker sockets, bridges, pushrods, and oil return areas before closing the valve cover.

Frequently Asked Questions
Q: Why would I replace all 12? A: If one heat-aged plastic clip has failed, the remaining clips may be similarly brittle.
Q: Can a broken clip be left in the engine? A: No. Locate loose pieces and inspect nearby oil passages and valvetrain parts.
Q: Does this set include rockers? A: No. It includes only the 12 socket retainers.
Q: Is it Cummins OEM? A: No. It is an aftermarket set.
