Inadequate shocks for 37s?

I got a CCLB ford superduty weighing in at 7700 curb, 37" tires on steel 17x10 wheels. Probably 140ish pounds total.
Brand new monroe heavy duty shocks. Stock ride height.
First time driving the truck so I cant compare to anything else. But it feels to me the shocks are not able to damped the huge rolling mass vs a stock wheel.
When i go over bumps on the highway i get about 3-4 smaller jolting shocks after the initial bump. And dont get me started on washboarded dirt roads. Truck feels like it will shake apart.
On my old 2wd 91 cclb stock wheels when you hit a bump it just took it and nicely bounced up and down once.
This one liek i said, jolts 3-4 times after. Its not death wobble for sure. All steering components are new and steering is tight.

Thinking of bilsteins (cant afford kings). Plan on keeping it stock ride height.
can 4600 keep up with bigger tires? or do you need the 5100 for that?

bilstein just said yeah the 4600 will handle your tire fine, no other input or comments.
Ill see what fox says.
Im just not sure what its "supposed" to feel like. Ideally if i had a go pro i could see what is happening over bumps, but i dont.

or since im unloaded when this is happening, the shocks are overdamped for this condition. I have yet to put a decent load on it. Would it perhaps smooth out then?
