Rear lift question for 09 4WD

I just bought a used 09 Double Cab base model 4WD. The previous owner has installed the Camburg 2.5" coilovers with the Camburg A-arms and mounted 285/70's on 17" rims. He did not lift the rear however and the truck rides with the nose pointing up in the air higher than I would like. I think lifting the rear about 2" to 2.5" will give me the ride height I want. The question is, which method should I go with to lift the rear? As with most of us, money is tight right now so I'm looking for an economical solution but I don't want to go with a block or shackle lift because it seems like a waste when the guy spent $1600 on the front lift. This is my daily driver and I will do some 4-wheeling on the weekends and also load motorcycles in the back so I'm looking for a solution that will give me the best solution considering all that it will be used for. Oh, and the truck does have the 3-leaf pack in the rear and I'm familiar with the TSB thanks to all the posts on this site. Thanks in advance for your advice!

 

save a couple bucks and get a full-leaf pack

 

Yeah just throw on some AAL's and some 5100's and you should be good to go!!!
