OBS vs SD Hubs

Do OBS hubs fit a Super Duty?

To the best of my knowledge, the answer is no. This is because the OBS trucks used a traditional hub & spindle assembly, while the Super Duty trucks use a unitized bearing assembly. There are kits out there that will convert the Super Duty's unitized bearing assemblies to traditional hub & spindle units, but the kits are usually very expensive.

Are you asking about the hubs or lock-outs?

if you are asking about the locking hubs, get rid of the factory junk and get a set of mile marker 449ss hubs. direct fit and look nicer than the warn hubs.

Lockouts, I found a set of Warns for less than $20, but they are OBS and I am not sure if they will fit. I would buy the MMs if I could find them for $20

the mm hubs for $20 is'n gonna happen unless they are old and worn out or broken. and thanks for the comment. i liked the mm hubs because they are all stainless and they look better than the warn hubs. brand new, i think they were about $170. 449SS is the part #.

What is this talk about a conversion kit? Off Road Store: 4X4 Manual Locking Hubs - Supreme Stainless Steel - Fits Dana 50/60 - Mile Marker #449SS, Mile Marker 4X4 Locking Hubs and Part Time Conversion Kits, 449SS
Does this do the typical elimination/plugging of the vacuum lines? Does it do more? $35 more?

I went to the Warn website, and it lists the same lockout part number for both a 96 F350 and a 2002 F350. Might want to call Warn and ask,
or for 20 bucks roll the dice!

YOU DON'T NEED A CONVERSION KIT!

This is a common misconception. The kit is to covert from the OBS ratcheting automatic hubs, not the new style vacuum lock hubs. Just plug the vacuum line and go!

I just had a thought. I wonder if you could get a way with just unplugging the solenoid? Then you wouldn't have to figure a way to cap off or plug the lines. Just leave everything else connected.
