Superduty axles to fit 15s

[yular]

So I have 99-04 superduty 60 laying around and I know I can swap the 92-97 knuckles and spindles on these but what else would I need to change besides grinding calipers to fit 15 inch wheels ? Found a screaming deal on 44s on 15 inch trail ready beadlocks

The back space and width on a 15 is going to mean a lot in this decision, the breaks are huge, but if your running steel wheels and some kind of adapter to get to the 8x170 lug pattern there MIGHT be a chance…

That's a lot of work to downgrade performance for a possible solution.

Huge spacers. Are your only chance. The factory 16" steel wheels are already a knuckle hair from the calipers
