What you are looking for is unofficially called a Toyota 8.25 or 8.4. It’s also called a T100/Tundra/Tacoma differential. It can be found in five-lug, 2WD, V-6 ’941⁄2-’04 Toyota Tacomas and every ’05-present 2WD four- or six-cylinder Tacoma that we’ve peaked under so far. The six-lug version would work with different wheels, but it’s gonna be more expensive because Toyota guys want the six-lug axles as well. The four-cylinder 2WD ’941⁄2-’04 Tacomas have an axle with a smaller 7.5-inch ring-gear with 27-spline shafts that won’t be nearly as strong as the 8.4 that we prefer. Avoid it.
