Jk Rubicon 4:10 gears vs. 1974 Chevy 4:10 gears (pics)

I just happen to have both of these sets of gears laying here so I thought I would take some pictures for you guys. I know some of you hate Jeeps, but still might find this at least interesting.

(ignore the blue towel, my workbench is black so the pics of the black gears would be harder to see).

The left is a front 4:10 from a 2008 Rubicon. The right is a 4:10 from a 1974 Chevy 3/4 truck. Both front axles.
(and the dog fur is wolf hybrid, not cracks in the gears)

Ring gear bolts.

In reality all of Spicers front drive axles have vastly improved in the strength department as far as the carrier goes. The outters with unit bearings and ball joints across the board is what sucks. If there was a way to have a new Super 60 with king pins and roller bearings I would be all over that action.

Do they still have barrell nut adjusters like the 03-06 Rubicon axles did?

??? Are you talking for the carrier bearings like on a 14bff?

I just swapped gears in the Rubicon axles, that is why I have the 4:10s laying here. They are shims on the outside of the carrier bearings and shim under the pinion bearing.
