Got a Firestone coil-rite airbag kit a few months ago, Just now getting it installed. install only took about 2 hours. I have some tips for anyone thinking about doing this mod.

1. the instructions tell you to cut down the rubber cone that sits on top of the spring. cut them so that there are 2 segments left, rather than 1. If you cut down to 1, space where the bag fits will be too big and the bag will overinflate.

2. Disconnecting the sway bar by unbolting it from the axle rather that trying to mess with the connectors

Firestone sends enough air line to run 2 separate runs with individual schraeder valves. I opted to run a "T" fiting so this way both sides are equal pressure.

nice install...hope it helps balance your ride.

I ran airlift1000 for 2 years or so and they were pretty solid. Stiff ride but I didn't mind too much.

 

Just completed this install on my wife's 2003 4Runner and wanted to add my experience:

Followed DIHOWARD's advice along with the instructions and only have a few things to note.

- +1 on the T-fitting
- The sway bar was a pain to get back on since the one bolt didn't want to line up right. Loosening the opposite side helped get it to line up.
- I took the wheels off, easier to work with and will allow the axe to drop lower without having to raise the frame so high. Although, I failed to jack the frame up high enough, so I pulled out the spring compressors was easier than putting the wheels back on, etc
- I wish I knew a better way to remove the shock from the lower attachment (pried it off, beat it back on [just remembered I had pry bars, crap])
- Before you commit to putting the coils with bags back in, go ahead and pressure test the bag connections, hard to do the soapy water test with they are installed
- any decent bicycle pump will get you up to your pressure in no time (almost a psi per pump for me), so no need to drag out the compressor
- I didn't see an emergency brake connection to remove, but I did loosen a bracket that looked like wheel sensor cables maybe (passenger side)
