And fwiw the “third” support is not necessarily a bonus as frames designed for 2 points of contact. Doesn’t hurt because obviously we’ve all been doing it for a long time however it is not a better solution when it comes to frames stress
It doesn't need to be a perfect solution, it is a solution that helps in a couple ways, intended or unintended. Intended is to help suppord the weight of the load. Leveling or trimming the ride is another atribute airbags achieve. It is also obvious they mount to the axle which is directly connected to the ground through the tires. That gives the airbags a seperate load path direct to ground becoming a third independent point of support. Since they are airbags riding on the tires, it is also a dampened load point due to the airbags themselves and the tires. The airbags are independent of the springs and shackles.
