It is a 4x4. Some people use Toyota lift shackels for the rear. You could get an add-a-leaf or possibly a different spring pack. Others can expand on this, I dont own any 2.6s. The front, you will probably have to crank the torsion bars. If you lift it really high, the ride sucks, just 1-2 inches wont be bad. I have done it to all of my trucks and no problems with ride quality.
