It's not so much the amount of lift but the amount caster correction. If you did no caster correction you could go 6"+ without vibs, it would be a challenge driving it and probably would have death wobble.

Js on a truck with little to no additional weight ends up being at a height where caster plates should be used which then sets up the axle for a DV Shaft.

Js on a heavily weighted truck might get away with Slee's blue bushings and no need for a DC shaft.
