Slam Specialties ASCEND Height-Based Air Suspension Auto-Leveling System

Height-Based Air Ride Control for All Four Corners

Take control of your air ride with the Slam Specialties ASCEND Height-Based Air Suspension Auto-Leveling System. Four independent height sensors measure actual suspension position, giving ASCEND the feedback it needs to adjust each corner individually and bring your vehicle to the selected height.

Vehicle-specific calibration adapts control to your suspension's behavior, while the dedicated 17-button wired controller puts adjustments within reach without relying on a phone. Choose a polished or black anodized controller finish to match your interior.
