Clunk from rear

Got a noise. Me and my buddy both have tacos with the same suspension setup and both have a clunk from the rear over bumps. 6112 and 5160 for struts and shocks and darak leaf. Called ome and got shims and pucks for the springs and it helped but still there. All bolts are tight. Not the spare tire.
Running out of ideas. I read a guy added extra clamps that go around the leaf and that fixed it. Only difference between the trucks is that my suspension has 30k on it and his has 9k.Let me know what y'all think.

 

Sounds like your 5160s are topping out. Those shocks are only designed for 0-1'' of rear end lift and the Dakar packs yield approximately 2'' of lift...
