Air Lift 3P Air Management Systems

Air Lift engineers asked themselves: what would the ultimate air suspension be like? How would it combine an easy-to-use, reliable, and feature-rich system with powerful technology and beautiful design? Air Lift Performance 3P air management system is the result of three years of development and testing. It is the most advanced product Air Lift has ever created. The 3P combines pressure-based control with the ability to add ride-height sensing technology with the upgrade to height sensors. While both types of air management have been utilized before, this is the first product to harness the benefits of both systems—instantly improving suspension control, performance, and vehicle ride flexibility. (See notes on Model 27780 below) Kits include: * 3H/3P digital controller * Integrated ECU + manifold * Advanced electrical wiring harness * 60 ft. of 1/4 in. air line * Inline water filter * All wiring, fuses, hardware, etc. required for installation Model 27780 has additional features: In an effort to make the 3P air management systems more customizable to builders across the globe, Air Lift has introduced a threaded-port manifold. With the option of threaded FNPT ports, builders can create trunk-setups so stunning that they rival their vehicles' stance. This manifold allows builders to choose the fitting and air line option that best fits their needs and aesthetic. The threaded ports on the new manifold make integrating straight or elbow hard lines and/or threaded-steel braided air lines easier and safer, with less chance of damage to the internal O-rings. The threaded-port manifold is built with the same advanced technology as the push-to-connect 3H and 3P systems—high-grade, fully integrated components, a 32-bit processor for precise 4-corner control, built-in Bluetooth, and an intelligent accelerometer for accurate adjustments. With limitless mounting options and a simple, single harness connection, the manifold can be easily installed to the builder's exact specifications.
