J20 axles in a J10 - Driveshaft ?

Do my driveshafts need changed if I go to J20 axles?

I'm sure the front will work but what of the back?
What if I go with a 2"lift and the J20 axles?
How about a 4" lift with the J20 axles?
If I go with a 4" should I swap the pitman arm? It needs to stay highway speed safe as well.

This Honcho may be in Ouray next month. Currently it is all stock. This weekend it gets a thorough going over. If my springs(2 leaf up front) don't pass my inspection then I'm buying new springs. I really don't want to lift this truck much at all but would really like to run my spare set of J20 axles in it. That would allow me to slap on my 33" MT tires from my 1981 J20 for wheeling. I'm thinking 2" is enough clearance for moderate wheeling.
I'll then buy a set of street friendly 33" tires and mount on the slotted mags. Then I can interchange as needed.
I have nearly new shocks on the truck now is another reason not to go too high.


The Chero is going SOA so it will be my main hard wheeler this Honcho is just a stand in for now.

i bet there is enough slip in the shaft that you'll be fine.

If I remember correctly we used the same drive shaft from the Cherokee
on crom when we put in the J20 axles. We did have to get a U joint that had both sizes of bearings on it

It may have been because we used a scout Dana 20.

when i swapped in a set of j20 axles into my j10. the front driveshaft fit with only a 2" lift but the rear did not becuase of the pinion stick out more on the D60s that the D44s. Best thing to do is build it how you want and go from there. I'd try using the J20 driveshafts if posible.
