Air Lift ALP4 Electronic Air Control System

Air Lift ALP4 Electronic Air Control System:
(Part # 10040870)
(Part # 10040872, 2023+ Ford F-250/350/450 Pickup, retains OEM spare tire location)

The ALP4 from Air Lift Company is the most advanced air management system they’ve ever built. It is now available as a complete control package for Kelderman four-corner air suspension systems, replacing the Air Lift 3H. Like the 3H package, it pairs Air Lift’s electronics with parts Kelderman has used for decades in air suspension applications.

This is a height-based system. Kelderman ride height sensors at each corner keep the truck at your set height as the load changes, whether you’re loaded, empty, or hooked to a trailer. The controller and app display air pressure at each corner of your suspension, so you always know what’s happening. Improved leveling algorithms learn your setup and filter out road bumps for smoother, more accurate corrections.

At the heart of the ALP4 is a compact, all-in-one manifold. It is machined from black anodized billet aluminum and houses the ECU, solenoids, and pressure sensors in one unit, so there are fewer connections and fewer failure points. In the cab, a 5″ full-color touchscreen controller in an aluminum housing gives you four programmable physical buttons for instant access to presets, manual 4-corner or axle adjustment, and air-out. The controller dims itself automatically for night driving. You can match the LED colors on the screen, buttons, and manifold to your truck. Use the free ALP4 mobile app to adjust presets, monitor the system, and fine-tune settings from your phone. The app offers better range and a faster connection than the 3H app.

New ALP4 features include:

• Valet Mode with customizable lockout
• Show Mode: full system use with the ignition off for one key cycle
• Low-draw Standby Mode for app control with the vehicle off
• Built-in diagnostics with plain-language system messages
• Compressor health test to track performance over time
• Adjustable pulse rate and preset-maintain sensitivity
• Slow Lift/Lower Zone for controlled movement near minimum ride height

The ALP4 system comes in a dual compressor/tank configuration and includes (4) ride height sensors, an air dryer, wiring harnesses, a weather-resistant compressor enclosure, the ALP4 manifold, and the in-cab touchscreen controller.

Optional Smart Terrain Leveling™
(COMING SOON!)

Add Kelderman’s Smart Terrain Leveling™ to your ALP4 system and level your truck on uneven ground. Whether you’re parked at a sloped campsite, a gravel pad, or a job site, Smart Terrain adjusts each corner of your Kelderman four-corner air suspension to bring the vehicle level, all controlled from the Air Lift App. It’s ideal for truck campers and overlanding rigs, or any time you need a level platform when parked.

Smart Terrain Leveling requires a Kelderman four-corner air suspension system.
