No. Adding air springs will not change the Weight Rating (GVWR, GCWR, GAWR) of your vehicle. Air springs simply increase your suspension’s ability to support heavy loads. Air Lift strongly recommend that you never exceed your vehicle’s Weight Ratings.
If they are properly installed and maintained, air springs can last indefinitely. Just check the pressure regularly, or use an on board air compressor system to maintain it for you.
Absolutely, air springs are engineered to increase ride quality when carrying heavy loads and help fatigued springs ride smoothly. Air springs greatly improve the ride of larger trucks.
No. The vehicle can be lifted on a hoist for a short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off the air springs.
Yes, you should always maintain the recommended minimum air pressure, even if your vehicle isn’t loaded. This keeps the air springs “in shape” and able to perform without rubbing or wearing. Check the air pressure periodically, as you do for your tires.
A compressor isn’t required, but it is convenient! An on-board air system allows you to inflate and deflate your air springs on-the-go. Compressors remove the hassle of pulling over or searching for service stations with air pumps. With some on-board compressor systems, adjustments are automatic and made with the touch of a button – all while driving!
