Dana 30 HP/LP Axel shafts
 

I've got both complete Axel's. But I just did u joints in the low pinion.

When I put my lift kit in in 7 days I'm going to swap the low pinion out for the high pinion.

Are the axel shafts that go into the diff the same on both? (Being that they're both Dana 30's)

Or do the high pinion shafts have to come with the high pinion?

They are the same.
