Hey Adam,

There's too many factors involved to give you a specific psi rating that's going to level your ride and give you a comfortable ride quality. The best way to determine the right psi would be to couple up the trailer, level the ride out, and then take it on a test drive to see if the suspension needs to be stiffer or not and changing the psi in increments of 5psi.

Hey Adam, how did things go after you adjusted the air pressure on your Tundra with the trailer hooked up? Sharing what psi range worked best could really help others dialing in their Air Lift setup for towing.

@LazerS It depends on how loaded I have the trailer and if it is windy or not. Generally, I set it at 15 -25. If the truck feels squirrely because of wind then sometimes I go as high as 40. Sometimes when you get to 40 though, the ride starts to be too rough. You also have to account for if you have a full truck of people or just 1 or 2 of you.

@AdamW Makes sense. That is the reason I like air bags though. They are the easiest way to get adjustable support when you need it! What kind of trailer are you towing?
