Rear upgrade options

[cumminz90]

The posi unit in the 93s going bad rather than fix the rear and chance something breaking again id like to put something heavier and better under there such as a dana 80 that wont go bad or hafta worry about breaking all the time. truck will see the sled quite a bit so i want something that will survive that and daily driving. Question is is there any other rears that would work good for this wear i could retain my 3.54 gear ratio? And wat type of vehicles are the dana 80s found? Thanks for the help in advance

your best bet is one from a 2nd gen dodge i know many came with d80s, and ud get disk brakes

Some of the 2nd gens used a 70 so check it out. Also the disk brakes are a fairly new thing. The older 2nd genners have drums.

2ndGens up to early 02 had outboard drums (think of a 1/2ton style drum removal).

If it had a 5spd and a diesel, or was a dually, with a diesel, it has a D80. The only ones that had a 70 were the 2500 autos.

when your looking at the trucks rears is there a big ( or distinguishing that you can you can tell right off the bat which is which) difference between the 70 and 80 Rear and thanks for all the info guys keep it coming

the 70's diff cover is almost a square/ diampond shape while the 8o is taller than it is wide

V10 5spd and duallys also had D80s
