Posi was offered as an option.
If its a z28, then yes. The base models did not include the posi rear end
Yes it does. It's called a limited slip differential. Posi would refer to the Chevy brand rear end. No you don't have posi. Yes you have a LSD.
The 3.73 rear end in a 1998 Chevy Silverado 1500 does not automatically mean it is a posi-traction (posi) differential. Posi-traction refers to a limited-slip differential that allows both rear wheels to spin together for improved traction. You would need to confirm with the specific vehicle's build options or VIN to determine if it has a posi rear end.

The quickest way is to jack up the rear of the car or truck and turn the rear wheel 1 complete turn and see how many revolutions your pinion yoke turns. if it makes thee revolutions and a little over it could be a 308 four turns and a little over would be a 410 ect..
its a posi tract.
