I searched first and found a couple threads with people asking the same question but I couldn't find an exact answer

I'm picking up a parts truck today, 01 2500 2wd quad cab short bed
I looked at it last night and grabbed the vin to get a build sheet on it
Running the vin the info for the rear axle is
4.10 Rear Axle Ratio
200MM Rear Axle
Anti-Spin Differential Rear Axle

I understand the gear ratio and anti-spin parts. But what rear is that?
I thought 2500's had Dana 70's in them. The other threads said something about it being a mistake because 200mm would be too small, but nothing pointed at what the axle actually is.

 

2500s came with dana 60s, except diesels, which I think we're dana 70s.

My truck has a 98 undercarriage with dana 60s front and rear, but here is what my build sheet shows:

DDP 5-Speed Manual Transmission
DHHS Shift-on-the-Fly, 241 Transfer Case
DJFS Dana M60/248MM Front Axle
DMF 4.10 Rear Axle Ratio
DRDP 200MM Rear Axle
DSA Anti-Spin Differential Rear Axle

Maybe someone else will chime in and tell me I'm wrong, but I'm pretty sure that's a dana axle under there.

 

V-8, and it will be D60, V-10/diesel with auto, will be D70, V-10/diesel with manual, and it will be a D80. The 200mm axle is the D60.

 

Ok thanks

 

If you are not sure just look at the axle pumpkin, The model # is on all dana's.
