Rear end... dually vs single ?
 

can anyone get me pictures of both ?

i'm thinking about doing a dually conversion and one guy told me i didn't have to swap rear ends... :P

to do it right you need to swap rear ends. but ive seen it done without changing rear ends. its all about the backspacing of the wheels. and i believe someone out there makes a hub adapter for the dually wheels

how much difference is there in cm or inches ? dually rear is wider ?

its better just to swap them out

its enough of a difference, an inch or two. Swap axles. You'll be happier in the long run, plus you'll probably get a Dana 80 outta the deal.

and the dually rearend is a direct bolt in. i have done one myself

Why wouldn't you just BUY a diesel? it's gonna be a lot of work (and work that you will never get your money back outta) to swap in the axle, the new tires, spacers, and the fenders. And the truck still wont be a 1-ton like any other dually on the road just because you swap rear axles and fender flares ;)

the only difference in the 2500 and 3500 is the rearend. same frames, motors, trannies. the 2500 does have smaller calipers but that is easily changed too. i made a 2500 into a dually and if he already has a single wheel and he knows this truck then why would he trade it for a dually that he knows nothing about.

1-tons have better suspension too. And I'm not sure for these EXACT trucks, but typically they have better cooling, better trans/gearing, etc.

i have a 95 2500 and 96 3500, they are they same except for the rear ends and the beds, same 3.54 gears, same leaf springs, same motors, etc. the 3500 does has overload springs, the only draw back to making a 2500 into a 3500 is that a true 3500 will be able to legally haul more due to dif. numbers on the cabs vin tag

sorry for the hijack but I'm goning the other way with this till my dually rear gets rebuilt can I use my dually rims on the 2500 axle?I got my hands on one cheap so I figure I can throw the 2500 axle under the truck till I get a chance and money to rebuild the 2500.

from my under standing all the 3500 were dulled with an 80and the 2500 was a single with 70 or 80

im certain you can but im not sure what you need to do to do it
sombody will hop on this thread and tell you what you need to swap it

ya the 3500 rims will go on the 2500 they will just stick out a few inches more, as for what axle is on what 2500 autos came with 70, 2500 manuals come with an 80, and all 3500 have the 80

sawmillman is your truck 4x4?, if so make sure the gearing in the front axle is the same as the one you are putting on the rear end or just dont use 4x4 if they are diff. the dana 60, 70, and 80s have diff gears, i have seen 60s and 80s with 4.10 and i alsos had an 80 with 3.54s and a 70
