What are my options as far as a locker or limited slip for my rear of a 2018 1500? What rear end is under there?

Detriot/Eaton True Trac and you have the ZF diffWhat are my options as far as a locker or limited slip for my rear of a 2018 1500? What rear end is under there?
I've been putting 572 rear wheel torque through one for 6 years now,with roughly 600 1/4 mile passes on it,i haven't been able to hurt it,lolI also had the TrueTrac installed. My truck is no longer a one tire fryer
But seriously it works great and is supposed to be bullet proof.
The dealer rebuilt my factory 3.21 geared limited slip twice under warrenty,before i stepped up to a True Trac.Not sure why you think 3.21's don't need limited slip,even way back when my truck was basically stock,it'd spin the snot out of the rear tires. Even with 3.21's ,you still have a torque multiplication of 15.1:1 in first gear with the 8 speed,which gives you roughly 6200 lb-ft applied to the rear tires (15.1 X 410 lb-ft = 6191 lb-ft),we could only dream of having that kind of torque applied to the rear tires,back in the 4.10 gear and 440 days. First gear in a 727 is 2.45,even with 4.10's that's only a torque multiplication ratio of 10:1,you would need a 440 making just over 600lb-ft to match the same torque at the rear tires as our 5.7's are putting to the rear tires in first gear with the 8 speed.I dare say there aren't many 440's putting out 600lb-ft,even now,let alone back in the heyday of the muscle car eraDoes anyone with a 3:21 ratio really need Limited Slip, except for snow ?
I have Limited Slip in my 3:55 ratio, because quite often i drive on wet clay
People with a heavy right foot & the 3:92 ratio should have Limited Slip or better differential
