Rear locker/limited slip

[Truckone176]

I have a 2021 eTorque 4x4 and the rear passenger tire seems to be the only tire that gets power. I would like to install a limited slip that actually works, any suggestions?

Do you have the e-locker button. Ext to shift knob?

I think the Detroit Trutrac may be your only option
