Airlift Performance ALP4 Kit for 21-23 BMW 4 Series Coupe (G22) Convertible (G23) and Gran Coupe (G26) with Front & Rear Performance Struts

Item SKU: ALP-78588-78688-27480-27804-2-KIT

This Air Lift Performance ALP4 kit is for the 2021-2023 BMW 4 Series Coupe (G22), Convertible (G23), and Gran Coupe (G26), pairing ALP4 management and a single compressor with front and rear Performance struts. It keeps the suspension package vehicle-specific instead of mixing universal air-management parts with unknown strut fitment.

• Vehicle fitment: 2021-2023 BMW 4 Series G22 Coupe, G23 Convertible, and G26 Gran Coupe.
• Suspension layout: Air Lift Performance front Performance struts and rear Performance struts. Both ends are included in this kit layout.
• Management: ALP4 pressure-based air management. It can be upgraded to height-based control later if that is the direction you want to take the setup.
• Manifold: The ALP4 manifold combines the ECU, solenoids, and pressure sensors in one anodized black billet aluminum unit. Less separate hardware to mount and wire in the car.
• Controller: A 5-inch full-color touchscreen controller in an anodized aluminum case, with four physical buttons for direct control.
• Air supply: This configuration uses a single compressor.

ALP4 gives you pressure-based control from the touchscreen, while the front and rear Performance struts replace the factory suspension layout with Air Lift Performance hardware made around these G22, G23, and G26 chassis applications. This stuff is about being able to set ride height for the road, then bring it down when parked, without treating the system like a universal kit that happens to fit.
