The rear gate type that opened out from the center could open out to a full 90 degrees, which was convenient for loading and unloading luggage. The rear combination lamp was arranged vertically and put on the lower side of the body in the FJ56V. The square lamp that is mounted a bit higher than the waistline was the design for the FJ55V.

The F-type was based on the F-type engine from the 40-series, but with improvements in the shape of the combustion chamber, intake ports, and intake manifold, as well as the addition of an exhaust cleaning apparatus.

The FJ56V had a body type that was only produced for sale in Japan, but the vehicles for export took on the 2F-type engine instead of the F-type, and also took on the name FJ55V. There are many differences in the outside appearance of the FJ56V and the FJ55V, with the FJ56V having a larger bulge in the engine hood, as well as the same combination lamp parts as used in the 40-series, but with the triangular windows abolished.

The front axle used a Birfield type ball joint, had an increased steering angle, and used truck leaf springs that were the same as those used on the Toyoace and Stout. The rear axle had many parts in common with the FJ45V.

The FJ55V was the first Land Cruiser to use a box-type enclosed structure for the side frame. It had a reduced number of cross members, making room for the drive train mechanisms. With just 3 cross-members, the front bumper and transmission under cover served as double function as substitute cross-members, thereby increasing the overall strength of the frame.
