Couldn't load pickup availability
The Rago Fabrication Wifey Air System is a complete on-board air kit that airs up or deflates all four tires simultaneously, using 3/8-inch high-flow lines rated for 170 psi. The kit includes every plumbing component needed to connect to a single or twin ARB air compressor and deliver gauged pressure to all four wheels. Two variants are available: SUV (120-inch wheelbase) and Truck (120-inch-plus wheelbase).
Simultaneous Four-Tire Inflation and Deflation
Airing down before a trail and airing back up at the trailhead are two of the most time-consuming parts of an overlanding day. The Wifey Air System routes air to all four tires at once through a billet aluminum distribution block and 3/8-inch high-flow lines, cutting air-up time to 4–9 minutes depending on tire size, starting pressure, and whether a single or twin ARB compressor is used. The same setup deflates all four tires simultaneously, so time spent at the trailhead gate goes toward the drive, not the prep.
Components Built for Sustained Use
Every fitting in the Wifey Air System is solid brass; the inlet line is braided stainless steel. Both materials hold up to corrosion and the mechanical stress of repeated pressurization cycles. The distribution block is machined billet aluminum, and the slide valves are rated for the system's 170 psi working pressure. The 3/8-inch high-flow air lines move volume quickly enough that the compressor is not the bottleneck on inflation time.
Gauged Pressure at Every Corner
The Wifey Air System is designed so that tire pressure at all four wheels is visible while the system is connected, not estimated from a single inline gauge. That means a builder can confirm each corner is at target pressure before disconnecting, which matters when running different pressures front-to-rear or when one tire has a slow leak that would otherwise go unnoticed during a fast air-up.
Features
- 3/8-inch high-flow air lines: rated for 170 psi, sized for fast volume delivery to all four tires
- Braided stainless steel inlet line: corrosion-resistant and built for repeated pressurization cycles
- Solid brass fittings and chucks: full-metal connections throughout the system
- Billet aluminum distribution block: routes air to all four wheels simultaneously
- High-quality slide valves: control airflow to each line independently
- Single or twin ARB compressor compatible: works with either ARB compressor configuration

Who This Is For and Isn't
The Wifey Air System suits overlanders and off-road builders who already run or plan to run an ARB on-board air compressor and want a complete, pre-sourced plumbing kit for simultaneous four-tire inflation and deflation. It is sized for vehicles on a 120-inch or longer wheelbase and is best suited to builders with plumbing and air system experience, or those working with a professional installer.
The Wifey Air System does not include an ARB compressor, Rago ARB Compressor Mount, Wifey Block Mounts, or Air Mounts. All are sold separately and required to complete the system. Installation instructions are not provided with the kit. The system is not intended as a standalone plug-and-play solution for builders without prior air system experience.
Common Questions
What components are included in the Wifey Air System kit?
The Wifey Air System kit includes a braided stainless steel inlet line, solid brass fittings and chucks, a billet aluminum distribution block, high-quality slide valves, and 3/8-inch high-flow air lines rated for 170 psi. An ARB compressor, Rago ARB Compressor Mount, Wifey Block Mounts, and Air Mounts are not included and must be purchased separately to complete the system.
Which ARB compressor does this system work with?
The Wifey Air System is compatible with both single and twin ARB air compressors. The compressor itself is not included in the kit. Inflation time for all four tires ranges from 4–9 minutes and will vary depending on whether a single or twin ARB unit is used, along with tire size and starting pressure.
How do I choose between the SUV and Truck variants?
The Wifey Air System is offered in two variants based on wheelbase: the SUV version is sized for vehicles with a 120-inch wheelbase, and the Truck version is sized for vehicles with a wheelbase over 120 inches. Select the variant that matches your vehicle's wheelbase to ensure the air lines reach all four corners.
What is the pressure rating of the air lines?
The 3/8-inch high-flow air lines included in the Wifey Air System are rated for 170 psi. This rating applies to the blue hose included in the kit. Verify that all connected components, including the ARB compressor and any fittings, are rated for the pressures used in the system.
Is professional installation required?
Professional installation is highly recommended for the Wifey Air System. This is not a standard DIY project; it requires experience with plumbing and on-board air systems. Installation instructions are not included with the kit, though a reference install video by "sponsoredbywifey" is available on YouTube for review before beginning the build.
