not sure on that Bebe... would have to try it
However, I would think higher rate spring or TBs will place more demand on the shocks as the shock absorption rate of the shock will remain the same. This seems to me like it would worsen the body roll IMHO.
IMO, the best way to reduce body roll with cranked TBs would be stiffer sway bars and bushings, stiffer shocks and bump stops that touch the control arms like OEM. Keep in mind stiffer sway bars will reduce articulation. I wish someone would produce stiffer sway bars with quick disconnect links
