There's a few different ways to tell. Being that your truck has the Tow Boss Package the only option for rear axle is the 4:30 Limited Slip.

If a truck has the FX4 package it will also be a mandatory item.

OBS trucks have axle tag on the diff. Code will have a "L" after the ratio. Another way is to jack up vehcile, both tire off ground, truck off in neutral, turn one wheel and have another person hold other wheel. An open diff will allow the other person to hold the wheel and not let it turn. LS diff will spin the wheel.

CW, make sure you get limited slip, for what little more it cost, it is well worth having.

There may be a LS issue with a 350 Dually that has not been talked about here. When I ordered my 2001 Dually through Bobby, if you wanted LS you had to go with 4:10s. Ford would not manufacture a Dually with 3:73s even if it was a 4X4 like mine was.-------Not sure if the same 3:73 issue still exists. I wanted the 3:73s for highway more than the LS on my 4X4 Dually.

Still the aame options on the DRW's:

3:73 Non-Limited Slip
4:10 Limited Slip
4:30 Limited Slip

If you want the Fx$ package it will require the Limited Slip

Get out in the dirt and stomp on it...

Look back to see if both rear wheels dug. That should be proof!

The axle tag reads 3L73 (3.73 limited slip)

No L...no limited slip.
Of course if your oil was changed and the tag is gone...your limited slip is probably still in there ;)
