I installed these airbags professionally on a 2016 Ford Explorer. They fixed the rear sag right away, but as others have said their setup was a real bear. In the garage the car had to be jacked up and the coil springs removed in order to put them back. The compressor connections are not waterproof, so the compressor had to be mounted in the car. The pockets creak a bit, but the system is very easy to use.
