Good To Know

Q: Why do lever rockers wear out? A: They wear out over time due to high operating pressures, high friction, or inadequate engine oil lubrication.

Q: Is it necessary to adjust the valves after installing new rocker arms? A: Yes, a complete valve lash adjustment must be performed following any valvetrain disassembly or replacement.

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