Just Curious. Has anyone thought of portals?
The problem comes in with any type of streetability with the Unimogs portals. From what I've gathered, 404 axles have a near 7.5:1 ratio and the 406's up in the 9:1 area. Great for a rock pig...too much for street and mph. There's a company using the 2:1 NP203 reducer box and adapting it the other way to make it a 50% overdrive but I've heard that they are pretty noisey being driven like that. There is also some special hardware needed to convert the axles from the tube driveshaft design to an open u-joint design. Sweet Axles though...no doubt about it!!
