Stop blocks are mounted on racks supporting a sliding fifth wheel assembly on a truck/tractor for stopping forward or rearward adjusting movement of the fifth wheel relative to the racks at a selected position for distributing weight between the forward and rearward axles of the truck/tractor. The stop blocks each contain a pawl vertically biased downwardly by a spring for engagement with notches between adjacent teeth of the sliding fifth wheel racks. The pawl is moved vertically by a lever projecting out of the respective stop block for moving the block to a selected position longitudinally of the rack.
