The Tundra diff is definitely big for a 1/2-ton and more comparable to a 3/4- or 1-ton as is seen here; (clockwise from upper left) Dana 80 1-ton, '07 Toyota Tundra 1/2-ton, pre-'07 Toyota Tundra, and GM Corporate 14-bolt 1-ton. A limited slip differential is standard in the Tundra, though we're excited that ARB is stepping up to develop a rear selectable Air Locker as well as an Old Man Emu 2 1/2-inch suspension and a front Bull Bar. Plus we've heard rumor of a supercharger coming from URD for the 5.7L V-8 so the accessories market is definitely addressing this new 1/2-ton. However, we would love to see lower gearing options and a fabricated housing from the rest of the aftermarket so this big gearset could be used as a custom front axle for a solid-axle swap under the Tundra. That would be really cool.
