it's not suggested since the frame for a 1500 isn't strong enough for 25/3500 stuff. But, you can pull a dually rear axle from a 94-01. if you pull everything from the donor dually, it's just best to buy a dually and work on it.
Oh yeah that's true. It probably would be a lot easier and cheaper to get a donor. Thank you
You can swap 2500/3500 stuff over fine. A few people have done it, Merc225hp on here has done it no problems. Legally it will still be a 1500 however.
All you need is the rear axle and dually box, possibly leaf springs and hangars depending how you wish to mount. You could use your half ton springs and weld a new perch on the axle, however if I were you I would swap leaf spring perches over to your frame and use the 3500 leaves.
i knew that but if he wants to go into 3500 terriotry with towing and what not. it would be best to build the donor truck.

Oh ya absolutely, you're right on there!

Thanks everyone for the help. No I don't want or expect it to perform like a 3500 for towing or hauling. I'd like to keep the lift in the back, what option for the leaf springs would be easier to keep the lift?
Dont just think about the rear diff, you'd have to change out stuff in the front as well unless you want 5 lug in front and 8 in rear.
