I am looking to buy a locker for the rear wheels for my 2002 Silverado 2500HD 6.0L 2WD, the problem is that I dont know what differential I got. Any one that may know please post asap, I am getting a killer deal on a 11.5 in. Thank you for the help guys.

If you take off your rear wheels, do the axles stick out in the center?

 

Yes, I do have Floaters.

 

You would probably just be better off putting a whole new diff. in. Go to Yukon and buy a true posi. From my experience with lockers, they are hard on the rearend. My buddy has a 99 z71 and he had a rearend explosion. So we got a Yukon true posi and put that bad boy in there. He loves it and i think it made a hell of a big difference when it comes to puttin the **** to the ground.

 

You have the corperate 14 bolt. It is a 10.5" rear gear.
