Air Lift Compressors: Single-Path vs Dual-Path Systems

An onboard compressor lets you adjust auxiliary suspension air springs without finding a separate inflation point. The important choices are whether both rear air springs should change pressure together or independently, and whether you prefer in-cab analog controls or a wireless remote. Air Lift sells these systems separately from the air springs themselves. This guide identifies seven compressor-system MPNs without assuming they will fit every truck or air-spring kit.

Should the left and right air springs adjust together?

Single-path systemsThe two air springs share one controlled air path, so they inflate and deflate together at equal pressure. This is the layout for 25592, 25854, 25980 and 25980EZ. It is a sensible arrangement when separate left/right balancing is unnecessary.
Dual-path systemsIndependent left and right lines permit unequal pressures where the supported load requires side-to-side adjustment. Air Lift identifies 25856, 74000 and 74000EZ as dual-path systems. A dual path changes control flexibility, not the vehicle's legal load rating.

Air Lift compressor comparison by MPN

Part number Family Air path Controller Included compressor
25592 LoadController II panel Single In-cab analog panel Standard-duty
25854 LoadController Compact Single Compact analog gauge Heavy-duty
25856 LoadController Compact Dual Compact analog gauge Heavy-duty
25980 WirelessONE Single Handheld remote / mobile app Standard-duty
25980EZ WirelessONE with EZ Mount Single Handheld remote / mobile app Heavy-duty
74000 WirelessAir Dual Handheld remote / mobile app Heavy-duty
74000EZ WirelessAir with EZ Mount Dual Handheld remote / mobile app Heavy-duty

LoadController 25592 uses an analog panel and standard-duty compressor. Compact 25854 and 25856 use an in-cab gauge and heavy-duty compressor. WirelessONE 25980 provides single-path control by handheld remote or mobile app; 25980EZ retains that control arrangement but has a heavy-duty compressor on an EZ Mount bracket. WirelessAir 74000 and 74000EZ provide dual-path wireless adjustment with heavy-duty compressors.

What does EZ Mount change?

Air Lift's EZ Mount versions combine the compressor and manifold on a preassembled mounting bracket. For the 25980EZ and 74000EZ, this reduces separate component mounting work and can simplify installation. It does not make the system a universal no-drill kit: the manufacturer specifies different fastener arrangements and warns that a universal application may not work with every vehicle.

These are compressor-control kits, not air-spring suspension kits. Check whether the vehicle already has suitable air springs, the required operating pressure, air-line routing and physical mounting space. Air Lift says its compressor systems work with its own air springs and most other brands, but exact suitability still depends on the installation.

Analog in-cab controls or wireless adjustment?

The analog LoadController options require a gauge/control location in the cab and appropriate routing between the controller and compressor. Compact 25854 and 25856 can fit an included gauge pod, a suitable 2â…›-inch opening or flush-mount arrangement. WirelessONE and WirelessAir use a handheld controller and compatible mobile app, avoiding air lines running into the cab. WirelessONE models also provide three user-defined pressure presets.

Checks before choosing or installing a compressor

  1. Identify the air springs. Confirm their manufacturer, pressure limits and minimum safe inflation. Never set the compressor to exceed the air-spring or system limits.
  2. Choose single or dual path. If the two springs must be adjusted separately to handle an uneven load, a single-path kit cannot provide that independent control.
  3. Check the mounting location. Measure space for the compressor, manifold and bracket; keep it clear of heat, water exposure, suspension travel and moving components as directed.
  4. Confirm the controller and wiring. Analog and wireless models need different cab arrangements. Use only the specified electrical protection, battery wiring and air-line connections.
  5. Check the EZ Mount hardware. Preassembly can reduce installation time, but mounting methods and drilling requirements vary by vehicle. Compare the exact kit instructions before ordering.
  6. Observe vehicle load limits. Air-spring pressure can help level an existing permitted load; no compressor or auxiliary air-spring kit increases the vehicle manufacturer's GVWR, axle rating or towing capacity.
