My first question is are the springs new as well? You stated in your earlier post the the shocks were new. Worn springs can put stress on your shocks.

My second question is what type of shocks do you have? The gr-2 or the agx? If you have the gr-2s they are about stock quality. Stiffer springs with stock like shocks is going to give you a more bouncy ride quality. Also have you replaced the rear as well?
