Upgrade shocks

What you’re probably talking about is the bouncing from contraction joints on concrete. 
The repetitive harmonic front end bounce. 
Not much you can do about it. A lot of weight transfer on a wdh will help but is the wrong answer the rest of the time. 
if this isn’t what you mean and the shocks are blown, different story, replace them. If you don’t know the difference, does it bounce when empty?  
But good shocks help in general.  OE shocks are soft. Not a bad purchase regardless.
