I have to agree with JeffW on one point and it's causing more stress on the hangers. The leaf springs have two halves. The front half from the axle to the hanger and the rear half from the axle to the shackle.

While the rear half will get less stress because of the action provided by the revolver, the front half will will cause more stress on the hanger because of the extra droop of the axle.

That stress however I think would be the same if you had an equivalent suspension lift and one wheel at full droop while the other is fully stuffed in the fender.
