Air Lift 27705 3P to 3H Pressure-to-Height Upgrade Kit

Convert Your Air Lift 3P or ALP4 System to True Height-Based Control

Upgrade your existing Air Lift Performance air management system with the Air Lift 27705 Pressure-to-Height Upgrade Kit. This plug-and-play conversion kit transforms your 3P or ALP4 pressure-based setup into a true 3H height-based management system for more consistent ride height, improved preset accuracy, and smoother day-to-day performance.

Unlike pressure-only systems, height-based management continuously monitors suspension position using ride height sensors. This allows the system to automatically compensate for passenger weight, cargo, temperature changes, and road conditions—keeping your vehicle sitting exactly where you want it every time.

Why Upgrade to Height-Based Control?

Height-based air suspension management offers a more consistent and predictable ride compared to pressure-only systems. Instead of estimating vehicle height using air pressure, the system measures actual suspension travel and automatically adjusts to maintain your saved ride height.

That means better preset repeatability, improved handling consistency, and a more refined driving experience whether you're cruising, towing, or loading passengers and cargo.
