So, my truck came stock with 3.21’s. I bought what I thought was a 3.92 antispin rear axle assembly and a front unit to swap out. I paid someone to swap the rear and I did a burnout afterwards and still had one wheel peel. I super curious now to even know if I bought a 3.92 antispin. The sticker is messed up. So how can I tell if it’s a 3.92 with antispin?

I can't answer your question, but I hope you have matching gears in the front and rear.

Can I count the teeth or something. What do I look for? I wanna make sure it is what’s is supposed to be before I swap the front to the wrong gear if it’s not what it’s supposed to be.

Someone correct me if I'm wrong. The anti spin isn't "locked up" at a dead stop. Torque is applied to both wheels, via clutch packs, once the truck is moving.

If you have equal traction to both rear wheels at a dead stop, and stomp on it, both will spin.

Confused yet? Look up some videos how it works. Made sence to me after I saw the cut away video.

I have the anti-spin/LSD and if I floor it on a hard surface traction will bounce back and forth between the left and right side. Now if I do the in grass/dirt both will spin.
