Description

Function of the Rocker Arm

The rocker arm transfers the camshaft’s motion to the valve, acting as a lever that pushes the valve open. It pivots on a shaft or ball, multiplying or redirecting the cam lobe’s force to actuate the valve at the correct time and duration. A worn or broken rocker arm causes valve train noise, misfires on the affected cylinder, and loss of power.

Why order it from Partszar

A worn engine part rarely fails on its own; it loads the parts around it until they fail too. Replacing it when the first symptoms show is what keeps a small repair from becoming a big one, and the engine runs smooth and quiet again once it is done.

• Fitment checked before it is listed. Every part is cross-referenced against the official parts catalogue and OEM part number so it fits first time.
