🧾 Overview
The Up Down Air Gen2 4-Tire Inflation System for 2018–2025 Jeep Wrangler JL and JLU models allows drivers to inflate, deflate, or equalize all four tires simultaneously, making tire pressure adjustments fast and efficient when transitioning between pavement and off-road terrain.
This vehicle-specific Gen2 Air Delivery System (ADS) mounts in the passenger-side engine bay, providing a clean installation while keeping the air management system protected and easily accessible. By connecting all four tires to the central ADS controller, the system automatically balances air pressure between tires while inflating or deflating.
The system can operate using a permanent onboard compressor or a portable air source connected through an external Schrader valve, offering flexibility depending on your onboard air setup. With DOT-approved 3/8" air lines, pre-cut hoses, push-to-connect fittings, and Betty Bar quick-connect chucks, installation is straightforward and trail operation is fast and reliable.
