AAM 9.25 and 11.5"

[034x4]

Anyone have ANY info on these: lockers, gears, shafts, u-joints etc.

11.5" is as big as or even bigger than a 14 bolt.

What about the 9.25" high pinion front? What kind of meat (tire) would this be able to handle?

I posted this in the newbie section and didn't get too much response. Wonderin' if the mopar guys can help me out some.

The 925 is basically a Dana 60 equivelant. The D60 uses a quarter inch larger ring gear (9.75) but the 925 has 33 spline outers stock, 1.4 inch shafts. The ujoints are total beef. 1480 equivelant. Precision 464 is the part number. Locker choices are limited but you can get an ARB for the front, and that's all I run in front diffs. I am not sure what other locker choices there are but I believe there are one or two others for the front. Gear choices are 3.73, 4.10, and 4.56.
The front axle would handle a large tire in most cases but it has hub assemblies, so I would not run anything larger than a 35 if you are using a full size. 37 if it's a lighter rig.
The rear 1150 is a red headed step child. A lot of people have it but there is not much out there for it at this time. ARB is supposedly working on a locker for it. They will probably be the first to release something. All you can get is a limited slip from AAM at this time, or weld it. Rear gear choices are 3.73 and 4.10 only. The 1150 is larger than a 14 bolt... it's basically a Dana 80 equivelant. 11.50 inch ring gear, some oddball rear shafts. They are course 30 splined 1.5 inch shafts with disc brakes.

Got any more brain busters?

I am not a Mopar man but AAM makes GM's axles as well so I know a little about your axles. The 11.5 rear is the same axle as the 11.5 GM rear "big 14bolt" in the HD's and Dually's with 35 spline axles. The 9.25 front is 33 spline axles and D60 sized axle joints, should be a pretty stought axle.

sorry djgaston, guess you got in a little ahead of me with quiet a bit more info. The GM 11.5 comes with an Eaton Locker so it should be a fit for the dodge unit, maybe.

I know that guys have used the GM 925 IFS ARB air locker in the Dodge axle just fine. But if the GM's 1150 rears have 35 spline axles, there might be some other differences in the rear.

I did find out that you can get the Eaton E-locker for the front diff as well.

You know what, I just thought of something. If you have these axles already, put them on here and on Pavementsucks.com for sale. Somebody with a 1/2 ton 2nd gen will probably buy them up. Then you can buy some better axles for your application that have more options.
If you don't have them yet, I would probably pass on them just because you have very little aftermarket support on them at this point.

I know from experience that the Dodge D60 front sucks. I know you asked about the AAM but there similar. The inners are 30 spline, the outers ore 30 spline. It has a dissconect coupler on the long side shaft, I wouldnt trust it for wheeling. The only thing that makes it different are the U joints and ring and pinion.

In most cases it will do just fine, but if your going to be gettin it off road I'd get a real D60.

I broke my short side inner shaft, although I was being dumb when it happened.

UM, the AAM axle is not a disconnect axle. As said, it has 30 spline inner and 33 outers.

Bash the Dodge 60 all you want, The later 60's were 32 spline inner, 33 outers and the mid 02 60's were non disconnect axle. The housing tubes, outers, are bigger than a "real" 60. Axles dont neck down as far as the ones I pulled from my HP60. Shaft at the CAD collar is 2". Biggest drawback is the unit bearing, but mine lasted 30K running 37 than a 42" tire.
