The movement is a front to back bounce... like the axles are the 2 pivot points and keep sending tremors back and forth between each other.
Harmonics?

Mate,
You don't have to be the Hulk to make it bounce.
Scenario 1 is I think the valving in the shocks are shot. If your only getting less than an inch in movement the oil in your shocks is not being allowed to flow through the valves.
The other sceanaro is when they put in the spacers they've put too much in and lifted the body too high, reducing the shocky travel.
To check travel, if your able, jack the vehicle up by the body, not under the axle, follow the following steps;
1.Car on flat ground in park, blah..blah...blah
2.If the shocky has a sleeve coming down over the body mark clearly and concisely with a chemi pen where the sleeve ends on the body.
3.Jack up body until wheel just leaves the ground.
4. Measure the distance from your mark to the bottom of the sleeve.
Carry this out on the back and front shocks.
Now I'm not 100% sure on full travel length, maybe someone (Tomp) can chip in, but I recon at least 3" and definatly more than 1".
Harmonics are effectivly a frequency, they can start with a long modulation and shrink to a short modulation cancelling themselves out, I think travel is more the cause in your case.
Let me know how you go.
