I need to replace my 8.55/ 10 bolt rear axle assembly, due to age, wear, whine, etc. I have access to both 8.55 and 8.92 ratio assemblies. My question is; are both assemblies interchangable?, i.e., length, shock and spring mounts, etc. And would the higher ratio improve towing ability?
I'm not looking to increase tow weight, only improving power. I'm aware of change in gas mileage. That's not an issue.

Ummm ...

8.55 is not driveable on city streets unless your tires are like 72s or something.

Did you mean 3.55 and 3.92?

But yes, 3.92 would be better for towing usually.

And as long as it's the same 8.25 or 9.25 rear axle and for 2WD or 4WD same as you have currently, it should be. Do have them check though; different years Dakota have different shock mounting schemes, and they changed lug patterns, so a 1988 won't bolt straight into a 2011, for instance.

Thanks. I didn't know if rear axles were like so many other parts for 02 Durangos. Many will work with any 2wd model between 1997 and 2003.

Now, see the "02 Durango 2WD" was information you didn't give. It's easier if people know that ...

But yes, pretty much.
