Limited slip only
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.
only if it came from the factory with a tow package
Yes, it could be ordered with GM's Posi-Trac as an option.
YES you can.
is it a posi rear end? big difference bteween them for procedure. yeah its positive
yes they came with a locker when they are in four wheel drive this option only came on the Z-71 offroad
Jack it up and spin one tire, if the other turns the other way you have a posi.SORRY, but i do believe if it turns the other way it 's non-posi, a posi would both turn the same direction[ tried many times at salvage yard] ,THE OPTION CODE is in glove box G-80 IS LOCKING DIFF.
its a posi tract.
No it will not, There are different size carriers for different rear end houseing
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.
No. Only if special ordered.
It can if it was ordered new with one or installed later on.
Most likely, however, it is easy to tell. Open the glove box, and on the inside of the door, you will see a white sticker with a bunch of letters, and numbers. G-80, is posi.
