Spring Constraints:
Create 2 spring contraints for the cube (sled) geometry
Translate 1 spring constraint -4 X and the other +4 X.

More Spring Constraints:
Create 2 spring constraints per cylinder and translate one +4Y and one -4Y (for each).
Create a null for both the upper constraints and a null for the lower constraints.
Position the nulls according to the Y axis of their respective spring constraints.
Free translations on the nulls.
Make the corresponding null the parent of the corresponding constraints (upper or lower) (See below)

Added Control:
For additional control, add more constraints per your needs. (see below)

Animate:
Animate the Null Controllers and playback the scene.
Adjust your springs and see how they enhance your scene.
Forward Springs

Rear Springs

This is a rough quick idea to get you started in the land of dynamic constraints!
