Re: Answer: IT DEPENDS.
Depends on what you do with the truck. If you are going to rockcrawl. No. Don't put 38s on them. If you are talking mud. Go for it. You probably won't have any problems unless you run lockers in mud then you may break something occasionally. I've researched this swap basically for the same reasons Shaggy looked into it. The weight issue and ground clearance were important things for me to consider. The C-clip 12 bolt rear end is not really very strong although Warn does have a full floater kit for it now with alloy shafts. If you break a c-clip axle without the full float kit, the wheel falls off. Just something you should know. Another problem with the 10 and 12 bolt is that they have crush sleeves. With a locker installed in the diff, this could be a problem. Open diffs probably won't matter. Someone recommended putting a 44 carrier inside the 10bolt. Unfortunately, the 44 carrier isn't all that strong for serious off roading either, and most people will tell you you need a detroit locker or some other carrier that is stronger than stock. Be leary of 3/4 ton dana 60 fronts and most rears. The axle shafts are no larger than dana 44's 30 spline 1.31" diameter. The only advantage is that the pig is bigger. The 1 Ton front Dana 60 is actually 240 lbs. heavier than a 44, and most have 1.5" 35 spline shafts (except newer models). If you do get a rear 3/4Ton 60 that is only 1.31" diameter 30 spline, you can always upgrade everything else with alloy shafts 1.5" diameter 35 spline if you upgrade to a 35 spline carrier as well. Replacing everthing in a front 3/4 ton for 1 ton stuff would get expensive fast, so just buy a 1 ton to start with unless you find a 3/4ton equipped with 35 spline 1.5" diameter shafts. Just my 'pinion,
