I can certainly provide you with the instructions for the Firestone Sport-Rite Air Helper Springs - Rear Kit, # F2320. You should inflate the springs to 50 psi, this will support a load of about 1,500 pounds. It is recommended that for the best ride, only inflate the springs enough to level the truck. Minimum inflation is 10 psi, maximum is 100 psi. The amount of air pressure in the springs will ultimately depend on the load. I have included a link to the instructions below. Page 4 discusses inflating the air springs.
