Lower the tire pressure to what you like
With 33" tires you have alot of sidewall, let it absorb some of the smaller bumps
With shocks removed, one end, jump on bumpers front and back to see how stiff suspension is now, shocks can't change that, shocks keep springs(torsion bar) from rebound bouncing, they don't support any weight.
So shocks can't make a ride better if suspension is too stiff now, shocks can make the ride stiffer if they are for the wrong weight or springs, that means they don't let the springs do their job.
Springs(and torsion bars) are set for the weight of the vehicle, if springs are rated for 2,000lbs and your vehicle weighs 1,000lbs(at that axle), then it will be a very stiff ride, weight of vehicle can't push down the spring, so might as well have a metal rod instead of a spring, lol.
Torsion bars are adjustable springs, so if you crank them "up" then their weight rating increases, which is why the front of the vehicle is lifted up, when you hit a bump torsion bar doesn't flex(twist) to absorb the bump, it just pushes vehicle up, so no "spring" type reaction to reduce energy transfer and you feel every bump.
Rangers have 1/2 ton bed rating, so they have 2,000lbs springs for 1,000lbs empty bed
Which is why they can be stiff when empty.
You can get 1,200lbs springs and then an overload leaf, overload leaf doesn't touch the frame until you get over 400lbs added to the bed, so you get better ride but don't loose weight rating
Get springs dialed in, then get the shocks you like
