Plain and simple: airbags for your truck help to balance the load. They're great for exactly that, they're not designed to increase your payload, they're designed to increase it a bit. They are designed to align your truck to ensure proper drive shaft and rear axle alignment. Extremely easy to install, hold air for at least a day without adjustment. I got them on purpose because they have bumpers, they ran without air for a while, no issues or issues. I only turn them on when I need them.
