Fandevok 4-Tire Inflation System - 155" Wheelbase Heavy-Duty Air Up/Down Kit with Digital Gauge

The FANDEVOK 4 Tire Inflation System is a heavy-duty air up/down kit that inflates or deflates four tires simultaneously for fast, accurate pressure control on-road or off-road.

Built for trucks, jeeps, ATVs and anyone who needs reliable multi-tire pressure management, this 155" wheelbase kit combines a metal manifold, a rugged 3-layer hose network and a backlit digital gauge to speed tire adjustments while withstanding harsh conditions. It’s designed to let one person set matching pressures quickly before heading into sand, mud, or remote trails, and to keep valves protected and hoses tidy in storage.

How quickly can I inflate or deflate all four tires at once?

The integrated 4-way manifold routes air to all four tires so you can inflate or deflate them together, saving time compared with individually switching between valves. The included ball and slide valve lets you fine-tune pressure and achieve automatic leveling so each tire reaches the same setting.

• Simultaneous inflation/deflation for 4 tires
• Ball and slide valve for precise, incremental adjustment
• US-spec quick-change couplers for fast hose connection
• Automatic leveling reduces manual pressure checks

Is the kit durable enough for off-road and temperature extremes?

The hoses are a 3-layer construction (PVC, braided mesh, rubber) rated to 300 PSI, engineered to stay flexible in cold weather and resist cracking in heat. The manifold has a high-strength metal body, rubber-protected joints and a shock-absorbing ring around the gauge to stand up to off-road impacts and repeated use.

• 300 PSI-rated 3-layer hoses for toughness and flexibility
• Metal manifold with anti-slip control knob for glove use
• Shock-absorbing gauge ring and protected fittings
• Manual quality checks and leak-tested components

How accurate and easy is pressure monitoring with the included gauge?

The backlit digital gauge provides clear readings up to 300 PSI with ±0.1 PSI resolution, helping you dial in precise pressures even in low light. It runs on two AAA batteries (not included) and is mounted so you can read all four outputs without fumbling between valves.

• Backlit digital display for night and low-light use
• High resolution (±0.1 PSI) for accurate tuning
• Central gauge placement for simultaneous monitoring
• Shock ring reduces reading errors from jarring impacts

What convenience and storage features does the kit include?

The kit comes with a compact carry bag, hook-and-loop straps for neat hose bundling, and four rubber valve caps to keep fittings clean and prevent debris ingress. These small additions make the system easy to stow in a vehicle and fast to deploy when conditions change.

• Carry bag sized for compact storage in trucks or trunks
• Hook-and-loop straps to prevent hose tangling
• Four rubber valve caps to keep valves free of dirt and gravel
• Quick-change couplers speed setup and teardown

Who this is for: The FANDEVOK 4 Tire Inflation System is aimed at off-road enthusiasts, overlanders, and work vehicle operators who need consistent, repeatable tire pressures across four wheels. It’s also a practical tool for anyone who wants to reduce the time and effort of adjusting multiple tires during trips, seasonal changes, or when towing and hauling. If you want a robust, compact kit that balances speed, accuracy and durability for repeated field use, this system is designed to meet those needs.
