Rear sag with 3" Revtech leveling lift

As I am the new guy on the forum page, this question may have been asked already, so I apologize in advance. I recently purchased a revtech 3" leveling lift for my 2006 tacoma 4x4. Unfortunately it seem to have reversed the affect I was looking for. Before I purchase the nose was down and wanted bigger tires, the lift was recommended, and now the rear sags. Any recommendations?

 

aal, new leaf pack, leaf tsb.

 

when you say a 3in leveling kit. how much did it raise the front and how much in the rear? the stock stance is only about 1/2in lower in the front so if it just raised the front 3 in, theres your problem. if it was actually a full leveling kit that raised both...idk raise the back more with 05tacoma's suggestions

 

It was a full leveling kit by Revtech. About an 1/1.5" in the rear and 2" in the front, all with blocks and spacers.

 

empty that would put it level front and back but with gas at 6.5lbs per gallon you probably have over 100lbs in the rear weighing it down. that could be the problem. the solution would be to either raise the back more or lower the front a bit. my vote is to raise the back with an AAL instead of a block because it will give you a much better ride
