Loud thumping from rear when going over bumps and rocks

[kenski]

I noticed that since installing my lift, I hear a loud thumping or banging noise when going over uneven terrain and speed bumps. If I crawl over the bumps, then it's not a problem. But if I hit a speed bump at say more than 5mph, then I can hear a bang just as I clear the bump.

I have a LE and for the rear I'm using SAW coils that's giving me +2". The xreas is still in place.

Are my rear shocks topping out. Will a longer rear LCA help? Any thoughts as to what might be causing this and how to correct? Help and advice appreciated. Thanks in advance.

Yes your shocks are over extending.

If you replaced the springs with SAWs and haven't replaced the shocks with longer travel ones, then you are over extending the stock shock (as stated), hence the clunk over bumps.

Solution: Ditch XREAS and upgrade to aftermarket, longer travel shocks.
