I am considering changing my ramchargers axles form half to 3/4 ton axles. If anyone has done this before your input on problems that may arise would be greatly appreciated. Will they bolt right up? Piniion angle? Spring location? Any tips and answers would help.
3/4 ton conversion

I made the swap to full one tons axles at both ends. If you use axles sourced from any Doge truck from 72 to 93, it will all bolt right to your springs.
Honestly the 3/4 ton front axle is the same as your 1/2 ton axle except it has 3 more lugs and slightly larger brakes. You won't gain any additional strength with a 3/4 ton Dana 44 but if you get both axles from the same donor truck, at least you'll have matching gear ratios and matching rims. Beware of unit hubs as these are weaker than standard hub assemblies with lock out hubs.
The 3/4 ton front will bolt in with no additional mods.
The 3/4 ton rear is likely a Dana 60. It's much bigger and rather strong. It too will bolt in place of your stock rear axle. However due to it's longer pinion, You will need to shorten your rear driveshaft and perhaps change the driveshaft yoke to match the yoke on the axle. You'll also need the U bolts for that axle as it has larger diameter axle tubes as compared to your stock Dodge axle.

The front and rear axles have bigger and more powerful brakes, which you should upsize to a 3/4 ton master cylinder and don't forget to replace the proportioning valve.
