really bouncy ride...

[aggiedave98]

While doing my 3" front/ 2" back lift on my '89 suburban 1/2ton 2wd, I put in I think like Pro-comp brand 2" lifted leaf springs. But now, my ride bounces all over the place and it's really annoying... is there anything I can do to help it?? I have a really heavy tongue weight trailer that I can get a hold of... would it help to tow that around a little bit to mash them down?? It's been 1.5 years now and they're still really bouncy...

thanks!
