lowered truck rides rough rough, need help

[AnobleL74]

Hi All
My truck has all new stock suspension, shocks etc, except springs.
it has been lowered, not exactly how, but guess shorter springs since all the other suspension parts are stock.
need advice on how to get a softer smoother ride,
i looked at our FAQ site but did not find anything
here are some photos so you can see the ride height.
