The GX and the 4Runner are both the same 120 series Land Cruiser Prado chassis, suspension, and drive train. They both share the 2UZ V8 similar to the one found in most 100 series, optional in 4Runner the 1GR V6. All of the V8's are full time 4WD in both GX and 4Runner whereas the V6 is selectable 2 or 4wd. Both Have the same A750F transmission as the 100 series Land Cruiser, FJ, Tacoma, Tundra, Hilux as well. PNut stated good benefits for both engines. The big difference is really which body style you like on that chassis since that's where your butt spends its time. The GX is essentially the same body as the Land Cruiser Prado 120 in VX trim level just with a Lexus badge and slight facelift, no rear tire carrier on door.
Both have 3rd seating row option I believe.
Both made in the same plant in Japan.
