Air Lift Performance 3P/3H to ALP4 Upgrade Kit Display & Manifold (1/4 NPT Ports)

The Air Lift Performance 3P/3H to ALP4 upgrade kit (display and manifold, 1/4 NPT ports) modernizes your air management for OBS air ride and bagged dually suspension on 1988-1999 Chevy & GMC GMT400 trucks. It is a plug-and-play swap for an existing 3P or 3H system: a full-color touchscreen display and an all-in-one ALP4 manifold and ECU.

Choose your fittings: no fittings or USB cable (Air Lift 27551 & 72550-W), 1/4" air line fittings plus USB controller cable (Air Lift 27380), or 3/8" air line fittings plus USB controller cable (Air Lift 27385).
