You're right. I re-checked... its R180 front, R230 rear. Still only a 7" ring gear up front. ROW gets C200 front, R248 rear.
This is very disheartening, and shatters my idea of building an Armada as a cheap man's Patrol overlander. I can't imagine how those tiny diffs are going to stand up the the 400 hp, deep 1st gear ratio, large tires, and high GVW.
Wonder if it's possible to swap in the M205 / 235 from the Titan / XD. Don't know what options are available for the rear, other than buying a legit Y62 rear end.
