Need advice on leveling kit

I own a 07 double cab long bed TRD Sport. It has been a great truck and after 88000 miles it is now due for a suspension change. I would like to basically level out the truck without getting into swapping out UCA's and maybe get a 1.5-2" lift in the process. My rear suspension has the upgraded 4 leaf from the dealer and I installed Firestone air bags with compressor and controller. The main question is which lift to go with without sacrificing ride quality as I do not go offroad very often, mostly highway driven and local NYC streets. Any advice will be much appreciated..

 

You could use 5100's and your stock coils. I have mine set to the 1.85" setting and I do not notice a difference in ride.
