When it comes to air suspension management, one of the most common questions we get is:

“Do you offer a height sensor system?”

The short answer? Not yet — but that’s by design.

At ONAIR, we’ve chosen to focus on pressure-based management systems, and for good reason. We’ve bagged hundreds of vehicles across all platforms — daily drivers, show cars, and weekend builds — all without the need for height sensors. Our pressure systems are engineered to deliver the ride height, performance, and reliability our customers expect — without the added complexity.

Here’s why pressure is the smarter, cleaner choice for most drivers.

💨 What Is a Pressure-Based System?

A pressure-based system uses the PSI readings from each air strut or bag to adjust and maintain ride height. These readings are instantly transmitted to the manifold and displayed on your remote or controller.

ONAIR systems — whether you’re running our 2V or flagship 4V digital setup — are tuned to balance accuracy, response time, and performance. You get real-time tank pressure readings, programmable presets, and a smooth, controlled ride without needing extra sensors or brackets.

⚖️ What About Uneven Loads? (Like Friends in the Backseat?)

One common concern we hear is:

“If I have people in the car, won’t the height be uneven?”

This is a common misconception. The pressure in each bag naturally compensates for load differences — especially when your system is well-calibrated. In real-world use, pressure-based presets do their job. Period.

Our team has installed pressure systems on everything from slammed show cars to family sedans. Whether you’re driving solo or with a full carload, the vehicle rides balanced and stable — with no extra inputs needed.

🛠️ The Reality of Height Sensor Systems

Height-based management setups rely on sensors mounted to each corner of your suspension. These sensors read vertical travel and send that info back to the controller. While it sounds great in theory, the reality is:

• Mounting sensors is invasive — You need to fabricate and weld custom brackets at each corner.
• Installation is complicated — Not every installer is willing (or able) to do it right.
• They introduce signal delays — We’ve spoken to pro installers who prefer pressure because the response is instant. With height sensors, the controller constantly checks and adjusts — creating lag.
• They can fail — Sensors are more vulnerable to weather, wear, and road conditions.

In short: more moving parts = more points of failure.

🔧 What if I really want a height sensor system? 

We hear you. For customers looking for that level of control, we do have exciting developments coming soon. Our 2V system will have optional height sensor brackets available — and if you’re someone who truly wants to go that route, we can discuss an upgrade path.

But for 99% of builds, a clean pressure-based system is the ideal balance of performance, simplicity, and reliability.

💡 Why ONAIR Stands Behind Pressure-Based Management

We didn’t just settle on pressure-based systems — we engineered them to perform at the highest level. Our manifolds are compact, efficient, and deliver real-time control. You get:

• 3 to 5 programmable presets
• Real-time tank pressure display
• Intuitive digital controllers (and Bluetooth app for select systems)
• Lifetime warranty and customer support from a team that bags cars every day

When you ride with ONAIR, you’re not guessing. You’re getting the system that works — every time.

In Summary

If you’re worried about the “what ifs” of pressure-based air ride — don’t be. At ONAIR, we’ve built a system that works for every real-world scenario, whether you’re slammed at a show or driving the squad around on a weekend cruise.

Less complexity. Faster response. Proven performance.

That’s the ONAIR way.
