Default Limited Slip?

How do you tell if you have a limited slip differential? I am researching synthetics to put in my vehicle and this question came up. Here is my rear diff from the build sheet.

The build sheet should show if you have it. If it's not on the sheet, you don't have it.

Do you see anywhere the letters LSD or the wording 'Limited Slip' in the same line as the word 'differential' or 'rear axle' ? If not, you likely don't have it.

2 ways to tell either way,
if your rear wheels are off the ground, like on a shop hoist, spin either rear tire, if the turn in the same direction, it likely has LSD
if they spin in opposing directions, then you don't

now if the truck is sitting on the ground, put it in low gear, push hard on the skinny pedal & release the brakes, turn the vehicle around & count the strips of burnt rubber, either 1 strip or 2

I like option 2 for checking for LSD... the cops have other opinions though, ones that I don't agree with.

General rule I go by: If you're asking if you have it, you probably don't.

Cd.....not all cops are against that method!!!! Just don't do it at the huge intersection during rush hour with Granny sitting behind you in her 1982 Oldsmobile. Atleast move into the parking lot.
