I had them on my toyota and really liked them. Never had any spring bending issues or funny ride issues and scarry endo issues at all.
That seems like it would cure the only problem I had with them which was axle wrap when they unload on climbs. A trac bar would also be on the list.I did add a center limiting strap so that they could not both unload at the same time but would still let each side droop separatly. Never had any spring bending issues or funny ride issues and scarry endo issues at all.
Also, 1/2 the weight of an axle plus a tire ~100lbs on a tire gives you a lot more traction than a tire in the air.
