<p><b>IN</b> Unimogs. That is to say, they’re about the only “abundant” vehicle we can think of that comes equipped with portal axles. Portals raise the centerline of the differential higher than the centerline of the wheels. Plus, they offer additional gearing reduction at the hub, which allows more of your torque multiplication to occur after the axleshaft, thereby reducing the chance of busted parts. <p><b>OUT</b> Where in the wide world of sports can you find Unimog portal axles even marginally as easy as you can find Dana 60s? And you know how hard it is to find good Dana 60s! And when you do find them, how much are they going to cost? And if you can afford them, how will you narrow them to fit your vehicle? It’s only a matter of time until some wacko fits portal outers to a Dana 60. Send us pictures when you do.
