The Jeep rides extremely rough because of the 4.5" lift. It's not a car, it is however a short wheel-based vehicle on arched springs. The best ride you will ever get out of a YJ is when it is on stock springs.
Track bars work on coil spring vehicles, they have no job at all on a leaf spring vehicle. Other than once they rust into place they have a tendency to stiffen the ride and limit flex.
65# is way to tight for a shackle bolt. I set the torque on mine to 40#, and I think that is still a little too tight.
