This gas strut provides controlled damping and lifting force for the rear window of the host tractor. It is mounted between the window frame and the cab body, supporting the window in the open position and preventing it from dropping under its own weight. When the strut loses gas pressure, the window will no longer stay fully open and may drift or close unexpectedly. This component is manufactured to match the original strut's charge pressure and stroke characteristics, so the window opens and closes with the same resistance as when the cab was new. On installation, ensure the ball sockets are fully seated on their studs and that the strut is not twisted during mounting.
