K3500 and K2500 Front Differentials

[oldbrown]

Good morning. I have 98 K3500 dually and looking to replace the front differential. I am finding a lot of 8 lug K2500 differentials. Do the K3500 dually and HD K2500 use the same front differential? Thank you.

Yes just make sure they are the same gear ratio as the one you already have

Thanks. Do you know from experience? Not doubting but just want to know for sure before tearing apart.
Yes, I will make sure ratio is correct

There are only 2 front diffs for these trucks, 8.25" 6 lug and 9.25" 8 lug.

Correct, I stated 8 lug in my initial note. I would think all 8 lugs are the same but the factories do some weird stuff. Thanks
