Height-Based Air Ride Management Kits ASCEND, Air Lift & AccuAir

airslamit • Air Management Guide

Your Stance. Your Settings. Your Control.

Four height-based air suspension systems. Four different approaches to control. Compare Slam Specialties ASCEND, Air Lift 3H, Air Lift ALP4 with height sensors, and AccuAir e-Level+ with Height+ to find the setup that fits your build.

Height-Based Leveling Saved Ride Heights 4-Corner Control

Every configuration compared here uses suspension-position sensors to help your vehicle return to saved heights as passenger and cargo loads change. Our ASCEND packages use the SV8C manifold, and our e-Level+ packages use the VU4 manifold. Air Lift 3H and ALP4 combine the ECU and valve manifold in one assembly.

AccuAir • e-Level+ / Height+ + VU4

Three Heights. Ready to Recall.

AccuAir Height+ TruPosition sensors provide suspension-position feedback for three saved heights. The separate e-Level+ ECU and VU4 manifold let you plan component placement around your installation.

  • Three programmable height presets
  • TruPosition height sensor technology
  • Automatic calibration with Height+
  • Height indication and adjustments through the e-Level+ app
  • VU4 manifold for individual four-corner air control
  • TouchPad+ control option; check selected package contents
Choose it for: three-height operation, AccuAir app control, and a separate ECU/VU4 layout.

Why Height Sensors Matter

Add passengers or cargo, and the same air pressure can produce a different ride height. Height sensors measure suspension position, giving the system feedback to adjust toward your saved height as the load changes.

Build your package: compare individual listings for included controllers, air-line sizes, tanks, compressors, fittings, and accessories. All four configurations require proper sensor mounting, wiring, plumbing, and calibration. Height-based ALP4 operation requires its height sensor upgrade; height-based e-Level+ operation requires Height+.
