How Much Air Pressure Should You Put in Your Air Springs?

9/16/2026

How much air pressure should you put in your air springs? There isn’t one PSI that’s right for every vehicle or load. The correct pressure depends on your vehicle, what you’re carrying or towing and the requirements of your specific air spring system. The goal is to use enough air pressure to help restore proper ride height and vehicle balance, not to reach a specific PSI number.

Air springs, often called air bags, are adjustable so you can change the amount of support as your load changes. The pressure that works when your vehicle is unloaded may not be right after you load the bed or hook up a trailer.

Here’s how to find the right air bag PSI for your setup, what happens when pressure is too high or too low and how to make adjustments for towing, hauling and everyday driving.

What Is the Correct PSI for Air Bags?

There is no universal air bag PSI that works for every vehicle, load or air spring system.

The amount of pressure you need can depend on:

As weight increases, additional air pressure may be needed to provide additional support. When that weight is removed, pressure can generally be reduced.

Instead of starting with a predetermined PSI, focus on restoring the vehicle to its proper ride height while staying within the pressure requirements of your specific air spring system.
