If you look at the top of this page it says:
150-Series Toyotas For the 2010-newer 2nd Gen URJ150 Lexus GX460, the 4th Gen J150 Land Cruiser Prado and the 5th Gen 2009+ Toyota 4Runner
150 series is the model code of the Land Cruiser Prado. The GX460 is a luxury version of that and is sold under the Lexus brand. The 4Runner, while not sharing the same body as the LCP/GX it shares the same chassis so we group it into the 150 series forum.
