This is demonstrably false.Same rear suspension, axle, diff.
None of this suggests that the 6th gen 4Runner is any 'beefier' than the PRADO.
The TrailHunter and TRD Pro will have the same rear differential as the GX550 - which is at least larger in diameter than what is on the US-spec J250. This was discussed ad nauseam elsewhere in these forums (and this thread).
While the easy thing to do is to say since these vehicles are "all the same TNGA-F platform", all is not the same. There are many differences (albeit many quite minor) between the frame, suspension parts, axles, differentials, fuel tanks, etc.
