trying to level my 04' z71 it has 2'' blocks in the rear was gonna just take them off but it looks like im gonna need new u bolts.if anyone has ever done
can you explain how or from where do i get the new u bolts.thanks

 

You can go to your GM dealer and order u-bolts for a 2wd and they will work fine. There are probably some places online to get them cheaper but I don't think they are all that expensive anyway.

 

Another option to level out your truck is to purchase some new torsion keys, to bring the front end up. As for the U-Bolts most automotive parts stores should have them or they can point you to a local place. Also checkout some 4x4 websites if you don't mind ordering them.
