Rear end stepping out over bumps

[caddyshackgolf18]

I have a 2018 Sierra crew cab and lately I noticed when I hit bumps on the road particularly when they hit my right rear my back end feels like it steps out on me. Similar to wheel hip. I have upgraded Bilstein 5100 shocks with stock everything else. I inspected the shocks and they still have pressure. I also checked u bolts and they were tight. Only thing I believe I noticed was that the right rear wheel seems to be missing some of the stick on wheel weights for balancing. Would an out of balance tire cause the rear end to get a little squirrelly over bumps? Anything else I should check? 
 

thanks

That's common with stiff shocks.....thats the only reason....out of balance tires would not cause that....its the shocks...live with it or add weight to the bed to force down pressure...Been there,  put HD shocks on my truck once and same thing happened..I got rid of them and went back to stock.

Good to know. I can live with it. Just wanted to make sure something else wasn’t going on.

If you want the functionality of a truck, this is the kind of ride you get over sharp bumps. It happens to me too from time to time.

Our truck's springs are rated to carry nearly an extra ton of weight. Try the hitting the same bump with 1000 lbs in the bed and you will find it does not happen.

This same question pops up time and again. People always think changing the shocks will fix everything. The leaf springs are as important as the shock to your ride. Our leaf springs are only being used at 25% of capacity when the bed is empty.

I think the bigger problem are the terrible roads in Pennsylvania where I live. Cold winter and warm summer makes for bad roads.
