Hey Venosho, how much did he charge to set you up for the 3.73's? I have a Dana 44 with disc out of a Grand Cherokee that i already cleaned and welded the mounts, just waiting for front gears to match. I'm either going to call him or make mounts to put in a Ranger 35 IFS, the splines are the same as our 30 shafts.

I'd like to see that, it sounds very interesting.

I havent been on in a while.  I called Arizona Differentials 602-462-5367 and brought them my frond axle and they installed my 3:73 gears with a new carrier and it works great. I think I paid $250.  I love the new gears and the all wheel disk brakes but I lifted the front to high so now I have to put longer A-arms ect. on it. It is not safe to be on the road right now....  >:(

So that is my next project for her and she sits in the garage.... AGAIN!

i called az diff. and had him ship the carrier and gear up to minnesota. After 2 months of i'll ship it tommorrow and 260 bucks i got the thing and not a chance it'll fit in the carrier. the ring gear he sent me is to big to even fit in if i machined the housing. i dont know what he did for you guys, but he may have just sent me something he had laying around to get me to stop calling. There is no evidence of machining he chargered 120 for on the carrier. i am going to drive 50 miles from my house there is a junk yard with a dana 35 independent front with 3.73's in a 97 ranger. splines are the same so i am going to use the housing and carrier off the ranger 35 and the axles, alxe tubes and cv shaft off the eagle 30. i will post how it goes.

If you have a 2.35 front D30, you can only run the 2.35 gears.  This differential case is a one off.  There are NO lockers/limited slips for this axle.

If you have any other ratio Eagle D30 front disco/nondisco axle, you have to use Jeep CJ gears because of the long pinion shaft.  The low/high differential cases from a Jeep CJ will fit and you could go down to 4.88's but I doubt the half shafts would hold up.  If the locker/limited slip fits the Jeep CJ, it will fit this.

This is a lot easier to remember than what doesn't fit.

The Eagle 3.54 gears and carrier are unique to the Eagle application, right?

But will 3.54 gears and carrier from other D30's fit?

The 3.54 gears and carrier are the same as the Jeep CJ's.  

Will others fit? Yes. Volvos, Aerostars, Just about any pre 86 Jeep Dana 30's.  There are a couple more.

If it's a tooth count of 46-13, for 3.54 gears, it will most likely fit.  The 39-11 tooth count, for 3.55 gears, won't work.

3.54 are usually listed as 46-13 and 3.55 are usually listed as the 39-11, but I've see both listed as either 3.54 or 3.55.

Dana 30 low ratio case 3.55 and Down. Dana 30 high ratio case 3.73 and Up.
