Air springs (also called air bags or air helper springs) supplement your vehicle's suspension to level loads, reduce sag, and improve ride quality when towing or hauling heavy weight. When your truck squats under a heavy trailer tongue or your motorhome rear end sags under basement cargo, air springs restore proper ride height and handling. Adjustable air pressure lets you tune the support for different load conditions.

What to Know Before You Buy

• Air springs are vehicle-specific—kits are designed for your exact make, model, year, and suspension type.
• Air pressure is adjustable: Add air for heavy loads, reduce pressure when empty to maintain ride comfort.
• Compressor kits add convenience—onboard compressors let you adjust pressure without an external air source.
• Air springs don't increase payload capacity; they improve ride quality and handling within your vehicle's existing ratings.
