What's recommended 2011 shock/strut replacement

Hi all. I have a 2011, 6' bed. Don't know much else about it.
Looks like it's all original suspension. Shocks are yellow.
Kinda drives like crap, being on the highway always feels like it's windy.
Recently replaced the wheels and it's not much better.
I don't off road, mostly highway driving and usually not a lot of weight in the back.
What are some good options on suspension replacement?

 

You can find some low mileage take offs from a 3rd gen. And get a slight lift in the process. You could also get some bilstein 5100 shocks and improve your ride i know it did with mine. You can also replace your control arms upper and lower that will tighten up your ride and absorb more road bumps. Im sure someone else can chime in with better knowledge of suspension and give some more info

 

Hey thanks that's a great start
