Product Overview

Automatic Leveling

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.

SmartAir II comes with a 60-day no-questions-asked money-back guarantee. If for any reason you’re not satisfied with SmartAir II, return it within 60 days for a full refund. SmartAir II is built with the same high-grade materials OEMs demand and is covered by a two-year warranty.
