It seems there isn't much info concerning the torsion bars on the Dakota and the Durango t bars available anywhere.

I'm using a 91-96 Dakota 4x4 chassis under a 49 Dodge pickup and I have the V8 bars rated at 2,000 lbs, but they don't seem to have the weight capacity I need, and for what I've read, those are as HD as that gen Dakota bars come in.

From what I've read, it seems the 98-2002 Durango uses the same torsion bars as the 97-2002 Dakota trucks use, but the Durango bars have a higher weight capacity and are suppose to be interchangeable with the Dakota bars of the same time frame. There is no place where I can find any dimensions of any 97-2002 Dakota/Durango T bars.
I'm hoping maybe someone can give me the measurements from a 98-2002 Durango torsion bars. I'm particularly interested in the V8 torsion bars (4.7 or 5.9 gas). I'm looking for the sizes of the hex head on both ends, the length of the bars, and the diameter of the bar through the center. A weight capacity would be a huge plus. If anyone has changed the bars between the 91-96 Dakota and the 97-2002 Dakota and the 98-2002 Durango, that would be great info as well.

So, to be fair, Here are the measurements for the 91-96 Dakota V8 bars:
Front hex measurements across the flats on the hex: 1. 50"
Rear hex measurement across the flats on the hex: 1. 50"
Length of the bar is: 50.00"
The diameter of the bars is: 1.125"
Weight capacity for the V8 bars is: 2,000 lbs.

There is a light duty torsion bar for the 91-96 Dakota 4 cylinder & V6 The V6 bars are interchangeable with the V8 bars on the 91-96 Dakotas.
Front hex 1.50"
Rear hex 1.50"
Length 50".00"
Diameter (from reading): .960
Weight capacity 1400 lbs

Thank you for any help. Gene
