Ive hooked up a 9 Netgain DC motor with 72V/1200A controller directly to
the rear driveshaft on a 2008 GMC 1500 (½ ton) truck. Very slow and low top
speed (20-30 mph?)

As I've been working on my differentials, I got to thinking about
what it would take to run my ev cj7 w/out a tranny or transfercase
(2 save weight and simplify).
I was thinking about running a larger dual shaft ev motor.
4.88 axle ratio
with these numbers, I'd be at 3742 RPM's for 65 mph.
I would hook up yokes directly to the motor shafts. I would only hook
up the front driveshaft to the front yoke when I actually need 4wd,
only the output yoke would be attached.
I'm not planning on running lithium batteries for weight savings.
One thing I'm trying to figure out is if I can get a strong enough ac motor.
I may go w/ a large reversable dc motor if necessary.
I'm trying to figure out if I ran this config, could I get out of my own
