So after 25+ years of living in Parma Ohio, Im moving to the big city of Windham Ohio. A while ago i bought a wrecked 2002 Durango for the motor and trans. and driveshaft and 9 1/4 and transfer case well, you know kept everything that wasnt bent. So as i look at a garage full of "why the hell did I keep that" and " As soon as i scrap it I'll need it". I wonder if i should just buy a bottle of Tylenol for my back and lug it to the new house. Hell, I still have the 7 1/4 from my fastback, and its going with us.

Since i have it...I figure i could always spool it, cut it and convert it to 5 lug for bracket racing.

But then i wondered how much power could that axle stand anyway. Since 8 3/4s are getting harder to find and become more expensive why not keep the 9 1/4 to beat on. Hell everyone use to chuck the 318 for a 360 now we have guys like 318willrun with youtube channels showing off their power potentials. (Keep up the good work!) Which i have one of those too, with the 302 heads. Pulled it out of a 85 ram, that i swapped for a 360. Back then i didnt know anything about the 302 heads...didnt know what i had, which is another reason I keep ****. Kept it just in case i blew the 360 in my 68.

Anyways, What do you think...
 
Do you still have the vehicle that you put the motor from the Durango in? If it's another Durango or a Dakota, I'd keep all that stuff. I don't know if it would be worth the trouble to swap the 6 lug axles out to put it in something else. I have an 88 D100 that I am removing the 9 1/4 out of, and replacing it with an 8 3/4 from a 70 D100. The 9 1/4 has Bonneville Salt Flat gears (2.45) and the 8 3/4 has 3.55 gears. I'm a semi hoarder of parts too, so I will put the 9 1/4 in the storage shed and let somebody haul it off for scrap when I kick over! LOL
 
The 9-1/4’s are also found in a be Ram trucks, which I’m sure you know. I see these trucks from time to time being built up and hauling *** pretty well. The rear will hold a good bit of power. It is a lot of effort to narrow a rear end down for an A body use. If you find it easy to do yourself then I’d keep it.
 
I dont know how to shorten one myself....but im could use it to learn.

Just keep it, you'll kick yourself later if you don't.
It doesn't take up much more room than your 7 1/4, so just put it on top.
You might even be able to sell it locally or trade it for something down the road.........
 
I had a 9.25” in an 84 Dodge Truck with 4.56’s and 39.5” super swampers. Beat it hard and never broke. The Dana 44 in the front on the other hand...
 
Put the ford 31 spline axle bearing ends and axles in it to eliminate the C clips. That would keep the 4.5 bolt pattern also.
 
I'm pretty sure the highest gears available in the 9 1/4 were 2.71's. The 2.45 was in the 8 1/4 and never in pickups

I never thought the 2.45 was available in the 8-1/4 truck axle, either. But I know someone who picked one up out of a D series pickup during a recent trip to Pa for his daily driver interstate cruiser D-150.

Mine came stock w/3.23’s. They were replaced w/3.55’s, still a factory gear ratio, though I’m not sure if it was a checkable box in the old days, it was a standard gear in the Durango in ‘98.

The 2.71 year set was certainly available for those long distance travels. A most helpful ratio for the Hwy. traveler. The don’t know how prevalent they were.

At least you can still get Suregrips and some decent ring and pinion gears for them.
 
The 2.71 9 1/4 gears were mostly in the 74 and up C Bodies and possibly the 400 and 440 B Bodies in the later years. The 2.45 8 1/4 I've only seen in the later A Bodies, F and M Bodies. Then there was the 2.24 in the later F and M Bodies.
