I recently put 22's on (285/45/22) and want to level out the back (2-3") as well as greatly improve the ride quality. As smooth as I can get it.

Can anyone suggest a good airbag system for the rear and a front shock that will compliment the back end?

I don't take the truck to the track or tow anything, just looking to lower and smooth out the ride. Will I need to drop the back with a shackle first? or can I inflate the bags to a desired height? I won't be inflating/deflating at all, so I don't need anything really "adjustable". Thanks.

 

You'll need a shackle for the rear because the leaf spring sets the height and the bag inflates from that point up. Bell tech makes a good kit and it is relatively cheap(around $250-300). Believe it or not I have adjustable ranchos on my truck and I love them, you can really dial in the ride quality to suit your needs. There around $80 each.
