Porsche Rocker Arm Shaft For Porsche 993 (1995-1998) Models.

A rocker arm shaft is a component in an internal combustion engine's valve train. It's responsible for transferring the mechanical motion from the camshaft to the valve lifters, which in turn open and close the intake and exhaust valves.

Key Components:

• Shaft: The main body of the rocker arm shaft, which provides support and rotational movement.
• Rocker Arms: Pivoting arms attached to the shaft, which are actuated by the camshaft lobes.
• Bearings: These allow the shaft to rotate smoothly within the engine head.
