If you're running an Air Lift Performance 3P or 3H air management system, you've already got one of the best air ride setups available. But Air Lift just released their new flagship — the ALP4 — and it's a significant step forward in nearly every way that matters. Faster processor. All-in-one manifold. Full-color touchscreen controller. Better wireless. Customizable LED lighting.

The good news for current 3P and 3H owners: you don't have to replace your entire system to get there. The new ALP4 Upgrade Kit swaps in the new manifold and controller using your existing wiring, air lines, and mounting — no rewiring, no full rebuild. It's the cleanest, easiest upgrade path Air Lift has ever offered.

Here's what the kit includes, what you gain by upgrading, and how to decide if it's worth the investment.

What's in the ALP4 Upgrade Kit

The upgrade kit ships with everything you need to convert an existing 3P or 3H setup to ALP4:

  • ALP4 all-in-one smart manifold (with built-in ECU, solenoids, and pressure sensors)
  • Full-color touchscreen controller with four programmable buttons
  • Air line fittings
  • USB controller cable

That's the entire upgrade — no extra parts to source, no separate ECU box, no controller harness to track down. Connect the new manifold to your existing wiring and air lines, mount the new touchscreen controller, and you're done.

What You Gain by Upgrading to ALP4

An All-in-One Manifold

The biggest physical change: ALP4 combines the ECU, solenoids, and pressure sensors into a single billet aluminum manifold. The 3P and 3H used separate components connected by wiring — clean, but more complex. The ALP4's integrated design means fewer connection points, fewer potential failure points, and a much cleaner install. It also looks like a finished product, not a wiring project — important for show builds and clean trunk setups.

A Faster Processor and More Memory

ALP4 runs on a significantly faster processor than the 3P/3H, with substantially more onboard memory. In practical terms, that means quicker transitions between presets, more responsive control, smoother app behavior, and headroom for future feature updates.

Full-Color Touchscreen Controller

The 3P and 3H used a small button-based controller with a basic display. The ALP4 controller is a full-color touchscreen with four physical buttons for tactile control — best of both worlds. The interface is redesigned with a modern, app-like layout that makes presets, manual four-corner control, axle adjustments, and instant air-out genuinely easy to access at a glance.

Customizable LED Lighting

Both the touchscreen frame and the manifold itself feature customizable LED lighting with multiple color options. Match your interior, match your build theme, or run a different color for show. Small detail, but it makes the install look intentional rather than aftermarket.

Better Wireless and Mobile App

ALP4 uses an upgraded wireless protocol with longer range and faster connection. The redesigned mobile app lets you control the system from your phone with the same UI as the touchscreen, and the system supports simultaneous controller and app use. For show builds, this means you can adjust your ride from across the lot or while the car is off in show mode.

New Features Not Available on 3P/3H

  • Valet Mode — lock the system at a safe ride height when handing the keys to someone else
  • Adjustable Pulse Rate — fine-tune how aggressively the system makes corrections
  • Advanced standby mode with ultra-low power draw for cars that sit
  • Calibrated height tolerances for hitting presets faster and more accurately

Still Pressure-Based, Still Height-Upgradeable

Like the 3P, the ALP4 ships as a pressure-based system out of the box. If you want height-based control, the optional Height Sensor Upgrade Kit (P/N 27705, sold separately) adds height sensors and unlocks automatic height maintenance regardless of load. Same upgrade path the 3P to 3H conversion offered, just on the ALP4 platform.

How the Install Works

This is the part that matters most to current 3P/3H owners: the upgrade is a drop-in swap. No rewiring required.

  1. Disconnect and remove your existing 3P or 3H manifold
  2. Mount the new ALP4 manifold in the same location
  3. Connect your existing wiring harness and air lines to the new manifold
  4. Replace your old controller with the new ALP4 touchscreen
  5. Calibrate the system per the included instructions

For most installers familiar with air management, it's a same-afternoon job. The kit is designed specifically to use your existing 3P/3H wiring, mounting hardware, and air lines — Air Lift engineered it as a true upgrade path, not a partial replacement.

Should You Upgrade From 3P or 3H?

Here's our honest take, based on what we've seen from customers upgrading so far.

Upgrade if you:

  • Want the cleaner all-in-one manifold look for a show build or refresh
  • Have noticed sluggish controller response or aging hardware on your current system
  • Use the mobile app heavily and want the improved wireless and UI
  • Want features like Valet Mode, adjustable pulse rate, or LED customization
  • Plan to keep your air ride setup for several more years

Stick with 3P/3H if you:

  • Your current system is working perfectly and you're satisfied with how it performs
  • You don't use mobile control or the new features wouldn't change how you drive
  • You're planning a major rebuild soon and would rather go ALP4 as part of that project

There's no urgency — the 3P and 3H aren't going anywhere, and Air Lift continues to support them. But for owners who want the latest features without the cost and labor of a full system rebuild, the upgrade kit is the cleanest path Air Lift has ever offered.

Available in Two Air Line Sizes

The ALP4 Upgrade Kit comes in two versions to match your existing air lines:

  • 1/4" air line version — for most enthusiast and street setups
  • 3/8" air line version — for builds with larger lines and higher flow requirements

Choose the version that matches your current 3P or 3H setup — you'll be reusing your existing air lines, so size compatibility matters.

Ready to Upgrade?

The ALP4 Upgrade Kit is the cleanest path from 3P or 3H to Air Lift's newest air management platform — no full rebuild, no rewiring, no compromise on what you already have installed. Most upgrades can be completed in a single afternoon.
