SmartAir II automatically levels leaf-sprung vehicles using a unique non-contact magnetic height sensor, which allows the system to intelligently determine whether the air springs should be inflated or deflated.
Increased Convenience - Eliminate the need to search for gas stations with a working air compressor. SmartAir II automatically detects changes in the vehicle's load and will make adjustments to the air springs as needed.

Easy installation- SmartAir II is easy to install with the included wiring harness. No air line or wiring needs to be routed into the cab of the vehicle which eliminates drilling into the firewall. Typical installation takes 2 hours or less.

  • Please note: This system will not work with Air Lift 1000 air helper springs

Air Lift - Air Suspension Specialists Since 1949

Air Lift Company is a manufacturer of air suspension kits (also called air bag suspension) providing the ultimate air ride for towing and hauling with safety and comfort. Air spring kits provide increased support while towing or hauling heavy loads. Our air bag suspension kits work with existing leaf or coil suspension systems to provide a safe, stable and comfortable air ride. Air Lift's air suspension kits include everything needed to fully and easily install, including the air springs, brackets, fittings and air line. Add an Air Lift on-board air compressor system to inflate and deflate your air helper springs with the touch of a button from inside or outside of the vehicle. Only Air Lift's Lifetime Warranty covers the entire contents of the kit, not just the air springs (also called air bags). We also offer an industry-exclusive 60 day No Questions Asked Money Back Guarantee on our air helper spring kits and compressor systems.
