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

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

This Air Lift Performance ALP4 kit is built for the 2019-2023 BMW Z4 G29 sDrive20i, sDrive30i, and M40i, using front and rear Performance struts, ALP4 pressure-based management, and a single-compressor setup. It keeps the suspension layout vehicle-specific rather than piecing together universal parts that may not suit the G29 chassis.

• Vehicle fitment: 2019-2023 BMW Z4 (G29) sDrive20i, sDrive30i, and M40i.
• Suspension: Air Lift Performance front and rear Performance struts for the G29 layout.
• Management: ALP4 pressure-based air management. The system can be upgraded to height-based control later if that is the direction you want to take it.
• Compressor setup: Single compressor configuration.
• Manifold: The ALP4 manifold combines the ECU, solenoids, and pressure sensors in one anodized black billet aluminum unit.
• Controller: A 5-inch full-color touchscreen controller in an anodized aluminum case, with four physical buttons for when reaching for the screen is not ideal.

For a Z4 that needs to sit lower without committing to one fixed ride height, this stuff gives you pressure control at the controller while retaining a complete front-and-rear Performance strut setup. No more treating the front and rear as separate projects or trying to make generic air hardware work around the G29 suspension.

The ALP4 management side uses an all-in-one manifold, so the electronic controls and air-valve hardware are kept together instead of spread across multiple components. The included management hardware is based around 1/4-inch air line, with fittings, wiring, a water trap, and mounting hardware included as part of the ALP4 system.
