Dakota brake upgrade suggestions

What is the story on the spindle swap?

Rancho used to sell a lift kit that had a modified spindle to give the truck 3inch of lift.

Sounds like a spindle change to allow bigger brake rotors. I did t know this, if such is the case.

Some guys swap the spindles from 2003-2004 (I think) to get different calipers an rotor size. I haven't research that option.
