Freeway Bouncing

[Skeeter1]

Sorry if this has been post before. I'm new to posting and I tried to seach to see if anybody had a similar post, but they did not seem to be the same problem.
I have an 06' F-250 PSD 4x4 with a Danahoe Racing leving kit. My problem is when traveling on some freeways going 60 mph or over my truck severely bounces from end to end. I just installed rear air bags and that makes the rear ride a little better, but it seems that the front just bouces to the extreme and I have to slow to 60 or under . Any suggestions??

Thanks!!
