Rancho makes a 1.5" leveling kit for Tacomas, uses new coils and shocks, the ride is very close to stock. If you want to go higher later you can use an additional 1" spacer with the coil.
I've had mine on for 2 years, 9 mos of that with a 1" spacer and I still like the way it rides, a little softer than a stock spring with a 2.5" spacer.
