The 4 runners have a notoriouisly soft suspension, great for driving kids around bad for towing. Originally I purchased some Air Lift helper bags and they leaked and never worked well the fittings were cheap push on plastic tees and the system quickly developed leaks. My compressor ran all of the time. I replumbed the system hoping to stop the leaking but it did not so eventually I pulled the bags out and tossed them. The Firestone bags were a replacement and they seemed to be better made heavyer material and best of all they use DOT approved Parker air line fittings. the bags slipped right in and the plumbing was a breeze. I did not like the two inlet system so i teed the two bags together into one service line to my compressor and after two weeks have not leaked a drop of air. The ride has been stiffened up a bit but now I can adjust the suspension for my load conditions!
