Airlift Performance ALP4 Kit with dual Compressors for 19-23 BMW Z4 (G29) sDrive20i sDrive30i and M40i with Front & Rear Performance Struts

Item SKU: ALP-76012-76512-27480-27804-27750-1-KIT

This Air Lift Performance ALP4 kit is built for the 2019-2023 BMW Z4 (G29) sDrive20i, sDrive30i, and M40i. It pairs ALP4 pressure-based air management and dual compressors with front and rear Air Lift Performance Performance struts, so the whole system is matched to the G29 layout rather than pieced together from universal parts.

• Vehicle fitment: For 2019-2023 BMW Z4 G29 sDrive20i, sDrive30i, and M40i models.
• Suspension layout: Front and rear Air Lift Performance Performance struts. This kit covers both ends of the car.
• Management: ALP4 is a pressure-based air-management system. The manifold combines the ECU, solenoids, and pressure sensors in one unit, which keeps the main management hardware in one place.
• Controller: The ALP4 controller uses a 5-inch full-color touchscreen in an anodized aluminum case, with four physical buttons for controls you can use without working through the screen.
• Air supply: Dual compressors provide the air supply for the system. That matters when you want the system to recover pressure without relying on a single compressor.
• Manifold construction: The ALP4 manifold is machined from anodized black billet aluminum and uses an LED-lit top cover with a rotatable logo plate.

For a G29 that sees regular road use, this stuff gives you pressure-controlled ride-height adjustment without giving up vehicle-specific front and rear strut fitment. No more treating the suspension and management as separate projects. ALP4 can also be upgraded to height-based control later if that is the direction you want to take the setup.
