ANTI-SPIN DIFFERENTIAL REAR AXLE?

Yes it's the same thing. There is only one factory LSD and it's the trac-lok

Thanks everyone. Yes the "ANTI-SPIN DIFFERENTIAL REAR AXLE" = LSD / Track-Lok.

I got 5.13 gears installed and will add the friction modifier in the rear when they're broken in..

I use hypoid gear lube with friction modifier in it. Why use two different things and why stock two different fluids?
I use the same fluid in all of my limited slip differentials up to the Jeep, and use fluid with modifiers in it for those.
Granted, the factory gears are already burnished and ready to go when they put the fluid in at the factory, but I've never seen a reason to operate limited slip without anything for the disks while gears are breaking in.
(some say it helps prevent new, unburnished gears, from getting too hot too fast)

(I'm using it now also, not just after break in)

I have Mopar's oil + the Mopar friction modifier they recommend.
