Having never done gears before.....a monkey could set them up in a 14bolt. It was super easy. The hardest part about the 14 bolt was cutting off the spring perches. And most people just give them away...$50 easy and spares are everywhere.
But I do agree that for the energy and $$ you'd put into a 60/14bolt swap...you could come in way less than that with upgrading your 80 axles and run a tire that large.
i only run 37s on my 1 tons....but will eventually go to 42s...and have no fear of breaking them
