Air Lift 25491 SmartAir II Dual Automatic Leveling System


Product Description

Fits Air Lift Helper Springs - Control 2 Springs Independently

The Air Lift 25491 SmartAir II Dual Automatic Leveling System automatically levels your leaf-sprung vehicle 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 only takes a few hours.
