I’m not a physics major but on the race cars I drove rear sway bars were used to loosen the rear end (more toward oversteer). We would disconnect them in the rain or you could not catch the back end fast enough. On a pickup with no load I would think the back end is inherently light, a rear sway bar might not be the best choice. On my 46 which has new leaf springs the front anti sway bar made a huge difference, it is a stiff one though. Chuck
