XJ on 37's

I ran 37x14.50s with a 4.3 Atlas, 4.88's and a healthy 4.3 Chevy in my old YJ.
The front 30 did fine, after I swapped to 30 spline shafts and Yukon Superjoints.
I ran ARB lockers in both the 8.8 and the HP30 and everything did great.
Never had any breakage after swapping over to the Yukon U joints, but before they went in I could break a Dana U joint at will (larger U joints with 27 spline chromo shafts).
I would keep you eyes open for guys selling good stuff for cheap.
I wheel in rocks, so am no doubt a little harder on stuff than you would be by the sound of it.
Just remember a complete imbecile can destroy a built Dana 60, so careful driving makes everything last longer. Joe Dillard also had a built Dana 30 in his rig, and he wheels some pretty severe stuff and had a 5:1 Atlas to boot. He never had a problem IIRC.
