Cornfed speed bump rear thunk

[Rishi3]

After installing my cornfed 3/2 on my 07 sport 4x4, whenever I go over a speed bump at more than about 5-8 mph, it sounds like the rear end just slams back down. Is this the nature of the spacer lift, or did I screw up somehow during he install (has been a few months)?

I didnt have the cornfed, I had the Daystar 1.5 rear spacers and mine would do the same thing. Would slam down violently. when going over speed bumps or anything of that nature.

To be honest, sounds like an install issue. I have the Daystar 1.5 on my rear and I go over 'speed humps' at 35mph and speed bumps at 10-15mph without a peep

My Daystar 1.5 in the rear is dead quiet as well. I have OEM XREAS shocks, don't know if that makes a difference.

Interesting. I don't see how there's much room for install error on rear spacers. Also for mine it really only happens on super aggressive speed bumps. I have XREAS as well. It happened on 04 sr5 as well.

Same issue with the thump too! I just noticed it after adding the spacer

That's what I thought too, how could I mess up? But mine happens on any moderate and above speed bump going over 5 mph. I also have xreas
