I use the Air Lift brand. I have run them for 10 years now on several different tow vehicles. Easy to install and they do the job. I would have a hard time trying another brand after living the performance of these ones.
The only thing I would, and will do, on any future ones, is the onboard compressor. It seems pricey at first, but in the long run the benefits of the convenience I believe would be worth it.
