{SOLVED}Lift on, now a clunking sound while going over bumps

Something not working right?

Hey Guys, I got my lift set-up done, MarkMC lift, Bilstein HD's all around and 285-70r17 Maxxis Bighorns (pics soon, I promise) And now when I go over big bumps, or even the curb out of my driveway, I get a clunk sound from the rear suspension. I have double checked everything, Its all tight, the spring doesnt move or anything. Could my shocks be bottoming out? Do I need to get the longer sway bar end links? Any opinions would be great, the Mrs. is all mad that the truck sounds "ruined" Thanks!!!

Check the tightness on the shock mount nuts... also, did you make sure to use washers to shim the lower mounts if you used the z71 shocks? Any looseness will cause clunking.

No, I didn't use the z71 shocks, But I did crawl under there and noticed the spring isolator wasn't all the way on there, recompressed the spring, moved it over, now the cluck is gone! Thank you for responding!
