Looks like they are using a Dana 44 front and rear. Open C’s and unit bearings. Four link with short arms a-la Jeep.
Depending on how similar it actually is to the Jeep set up there could be the worlds largest aftermarket suspension and axle upgrade options ready to go right off the bat! Including exotica like coil overs, Dana 60 one ton and portal axles!!!!!! All bolt in ready to go.
Smart.
