Abstract: A removable side shifter attachment attachable to the carriage bar of a lift truck has a frame shiftable with respect to the truck. The frame includes a shifter carriage bar for receiving a lift fork. A hydraulic cylinder attached to the truck carriage bar having rods contacting the frame at its sides is positioned horizontally forwardly of the truck carriage bar and between the truck carriage bar and the shifter carriage bar. The cylinder is positioned generally within a J-shaped portion of the shifter carriage bar so that the cylinder does not extend substantially above or below the carriage bar and does not appreciable add to the overall thickness of the apparatus. The cylinder further includes two axially aligned chambers separated by a central partition, each chamber containing a piston in contact with a respective rod, each piston dividing its respective chamber into interior and exterior portions.
