From what I have seen the only way to lift the nose of my 06 2500 Cummins 2WD is with the Daystar spacers, either 1.5 inches or 2.5 inches?

Does anyone have the part numbers on these parts?

The tires I'll be running are 285 50 22 and the rims are 22x9 with a 20mm offset, so they will stick out slightly but nothing major, but might look a little silly with the rake.

I would like to go with the 2.5 spacers and add a spacer to the rear leaf pack but have heard a few horror stories about using the larger 2.5 inch Daystars. Any suggestions?
