Front lower strut 2 inch spacers ?? 2007 suburban

Putting new front struts on my 2007 burb. I did order up a pair of 2inch spacers to put in at bottom of strut to level off truck a bit. Anyone try these ?? On my older chevys I would always crank up torsion bars a bit to bring up front of truck. I never had any camber castor issues from that. If any have tried these spacers on GM trucks or Suvs feedback would be much appreciated.
