Up Down Air 4-Tire Inflation System — Engine Bay Mount (Jeep Wrangler JK & JKU)

Overview

An onboard 4-tire inflation and equalization system designed for 2007–2018 Jeep Wrangler JK & JKU models. Mounted in the engine bay (driver side, rear), it can automatically equalize, inflate or deflate all four tires using a permanent air source or a portable pump connected via an external Schrader valve. All components are heavy-duty and DOT approved.

Benefits

• Save time — inflate or equalize all four tires simultaneously instead of doing them one by one.
• Drive with confidence — maintain consistent tire pressure for better handling and predictable performance.
• Protect your tires — consistent pressures help reduce uneven wear and extend tire life.
• Convenient on-vehicle solution — works with an onboard compressor or a portable pump for flexibility on and off-road.
• Less fuss at the trailhead — automatic equalization makes transitions between highway and off-road pressures quick and easy.
