Bolt in Axle Swaps -
TJ Swaps - Pretty much the only bolt-in axle swap for a TJ will be another TJ axle. So if you want a bolt-in Dana44, you'll have to find a TJ Dana44. XJ HP Dana30s are also bolt ins, and stronger than your stock LP Dana30.
YJ Swaps - There aren't really any bolt in axle swaps available for the YJ. Luckily axle swaps are much easier on leaf sprung axles.
