I had the same problem when I installed my BDS. Try the t-case drop instead of the SYE until the springs settle a bit. My problem almost disappeared when my springs settled down to real close to the 2" promised on the springs.
No sense in dropping big bucks if you don't need it. BTW, what size lift shackles?
I got a Jeep, it's lifted and it's got crap bolted to it.
