Air Lift ALP4 Digital Height & Pressure Based Air Ride Management System, 3/8″

Classic Aircooled VW Air Management Systems parts by Limebug

Air Lift have just released their most advanced air management system yet. Introducing the ALP4, a system designed by Air Lift to replace the hugely popular 3P and 3H control systems. Whether you’re chasing show-level fitment or seeking finely tuned air suspension control, Air Lift has long been one of the most trusted names. The ALP4 is Air Lift’s next evolution in air ride control, and we’re here to run through the new features and what you can expect.

What is the Air Lift ALP4?

The ALP4 from Air Lift is a pressure-based air management system that combines modern hardware, smarter algorithms, and greater customisation for your car’s interior. With a newly designed full-colour touchscreen controller and a fresh manifold design featuring customisable RGB lighting, the ALP4 has been built with personalisation firmly in mind.

Available in:

ALP4 Control System for 1/4″ air line – (SKU: 030010072)

ALP4 Complete Management System 1/4″ with Tank & Compressor (SKU: 030010174)

ALP4 Complete Management System 3/8″ with Tank & Compressor (SKU: 030010177)

Want even more precision? An optional height sensor upgrade kit (SKU: 030010415) lets you convert the standard pressure-based ALP4 into a fully height-based system.

What’s new with the ALP4 compared to the 3P?

Air Lift have made some refinements and some big upgrades. Here’s what really stands out against the still-popular 3P:

Full-colour touchscreen controller: 3.5″ display, four programmable buttons, and anodised aluminium housing.

Plug-and-play wiring: Not new, but important. The ALP4 integrates directly with existing 3P power harnesses, so upgrading is seamless. Credit to Air Lift for looking after existing customers.

Custom LED Lighting: Both the controller and manifold feature customisable RGB lighting. Match it to your interior or go bold with accent colours – it’s your choice.

New Mobile App: Redesigned for easier use, stronger reliability, and improved connectivity thanks to the manifold’s updated wireless protocol. Android and iPhone users alike should see a much smoother experience.

Smarter and Faster Internals:

Faster Processor – 3.5x quicker than before with 20x more RAM.

Improved Learning Algorithm – fewer calibration sequences needed when making adjustments.

Road Filtering Tech – helps reduce “preset hunting” while driving.

Compressor Performance Test – allows you to monitor compressor efficiency over time.

Valet Mode – lock the system at a preset height to stop others damaging your fitment.

Updated Show Mode – enables full use of the system for one ignition cycle with the vehicle off – ideal for adjusting stance from outside the car.

Adjustable Pulse Rate & Slow Lift Range – fine-tune your suspension speeds for precision control, particularly useful when dialling in fitment at shows.

Add-ons and Upgrades

Height Sensor Upgrade Kit (SKU: 030010415): Converts the ALP4 into a full height-based system.

Second Compressor Harness (P/N 030010103): For running dual compressors. Just like with the 3P, you’ll need the additional harness, but Air Lift make this a simple add-on.
