U992 universal joint in the heavy-duty 68x89x165.5 mm configuration, also searched as ZK6800 for SHACMAN F3000 propeller-shaft service. The photographed greaseable kit includes one forged cross with four installed bearing cups, four large slotted external retaining rings and one separate 90-degree elbow grease fitting. Confirm all three dimensions and the retaining-ring arrangement before ordering because rounded 68x166 listings may use different groove positions.
