Misc. Why is the rear axle narrower than the front?

[73CJ]

Can anyone tell me why the narrow track wheel to wheel is--front (53 inches) rear (50.5 inches)
and the wide track wheel to wheel is --front (56 inches) rear (54.6 inches)

I used spacer to make them the same

Has to do with wheel placement going around curves, alot of vehicles are designed that way

Humm never heard of doing that in design before.
I would think that it’s best for our CJs to follow the same track when running deep mud and snow. The rear wouldn’t be breaking a new track.

You can read up on "Ackerman angle" to get an understanding of why.

I'll be doing the same with my Franken-J, using a Chevy rear and possibly a wide-track front, so I'll add spacers to equal it out.
