Well , then you need stiffer springs along with packers. Higher ride height will help as well.
There still could be something wrong with packers, i remember there was issue with it in past , don't know if they fixed it.

 

My ride height setting was wrong, lower that and i'm hitting the bumpstop.

 

yep lower ride height means less suspension travel hence sooner the bumpstop will hit.
