OK peeps. let's see if we can answer his question now :cheesy1:

None of us have asked the correct question yet to give him the full answer. BD answered the question if he wants to lower the front & rear the same amount he has done to his.

We need to know specifics - drop the rear only, drop front & rear, slam it, 2"/3" F/R, etc.

I agree with MyBigToy in more info is needed as to how much tntwolt wants to lower his AV. personally I went with DJM 2" rear lowering springs (DJM P/N CS2007R-2) as I just wanted to level my '07 Av. Also as pointed out there are inexpensive ways but then there are the safe correct ways to do it.

The typical drop when you do that is a 2"/3" front/rear, which is what BD did so his advice is good for you. He doesn't remember the brand on his drop springs; I've dropped the rear of my truck 3" with Eibach springs (part number 3887-520; technically a 2.8" drop). In addition to the springs I added a DJM Suspension rear kit:

which includes shock lowering brackets and shorter anti-sway bar "dogbones". In addition I added DJM rear trailing arm drop brackets to correct the geometry on them. You will also have to trim, IIRC, one of the rear "bumps" off the rear bump stop.

The springs have settled out some in the 5+ years they have been on the truck so I recently added 3/4" spacers to bring the stance back up a little on the rear.

You could also go with a 3"/5" drop; these typically all utilize new front control arms whereas several of the 2"/3" drop systems use torsion bar keys, which are not recommended due to a poor ride.
