There are only two things that I know of that would cause this problem.

Too much air pressure in the tires and too stiff rear springs.

Check the easy one first. tire pressure. What does it say on the tires
is the maximum tire pressure. Don't exceed it.

Good luck.

My truck beats you to death at fwy speeds unless the pavement is very s
smooth.
If there are any expansion joints, it feels like the rear tires are
actually bouncing.
