I received the set last week and postponed the install until yesterday. I allotted the whole day to do the work. However, I found that this was a very easy install. It took 5 bolts and removal of the springs, this took about 45 minutes to complete both spring removals, modification to the bumpers and reinstall the springs, and the five bolts that I removed. The next 30 minutes were used in routing the air lines and mounting the valve stems. The instructions made things easy.

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!

Perfect Riding Height At Any Rated Capacity Load

The new air bags in combination with the new nitrogen gas monotube rear shocks gave us a superior ride with the perfect rear riding height at any losd within the rated capacity of the 4 Runner vehicle, from empty to maximum. The installation and instuctions were spot on with no complications. If you are mechanically inclined with the right set of tools, jacks, and stands, you should be able to install these air bags. The most difficult part of our job was removing the top nuts on the existing rear shocks since we were replacing them also on the 99 4 runner, due to the limited clearance and angles. Undo the lower nuts and let the shocks hang until the springs are out if you are changing the shocks. Otherwise, you don't need to undo the top nuts.
