Replaced air suspension in 99 now what?

I replaced the leveling system in EB EXPY and have springs in back and new shocks all around. The ride is very bouncey and at times rocks back and forth, What can I do next to solve this?

Check tire pressure and sway bar tightness.

might want to try better shocks then what came with the kit, atleast in the rear

if you installed the cheap ebay kit, its more then likely its the cheapo rear shocks, they use a real cheap gabriel type shock, which is onley good for something like a ranger or s10's weight
