# Do Airbags Actually Level Your Caravan? The Honest Answer > "Just get airbags, they level the van for you." It's the most repeated line at every caravan park happy hour — and it's mostly wrong. Airbags are a great ride upgrade, but at the price most vans carry they're manual, they only fix one of the two axes, and the nose is always the jockey wheel. Here's what's really going on. *By Ross Bolden — B.E. (Mechanical), Founder · July 2026 · 6 min read · Written for Australian caravanners* Canonical: https://ozlevel.com.au/blog/do-airbags-level-a-caravan.html --- ## The short answer **Partly — and less than you think.** Airbag suspension can raise or lower each side of your van to correct *side-to-side roll*, within a few inches of travel. That's the whole of what it does for levelling. It does nothing for the nose of the van, and on most kits *you* do the adjusting by hand while watching a gauge. Calling that "auto-levelling" is generous. As an engineer and a caravanner, I think airbags are worth buying — for the right reason. This article is just about separating what they actually do from what they get sold as. ## What airbags actually do Airbag suspension replaces or supplements your van's springs with air springs you can inflate and deflate. Its real job is **ride quality and load-levelling**: a smoother tow, less sag under load, and adjustable ride height for clearance. Those are genuinely good things, and the reason to buy airbags. Because you can inflate one side more than the other, airbags can also raise the low side of a parked van — correcting **roll**. But two hard limits apply: - **Travel is limited.** An airbag has a few inches of lift. A mild slope, fine. A noticeably uneven site, and you're back to putting a ramp under the low wheel. - **It's one axis only.** Airbags can't tip the van forward or back. The nose — pitch — is set entirely by the jockey wheel, every single time. ## Manual or automatic? The tiers tell the story Here's the part the happy-hour advice skips. Most airbag kits don't level themselves at all — you do it, by eye. Take Australia's most common system, Cruisemaster, tier by tier: | Cruisemaster tier | What you get | Levels on site? | |---|---|---| | Level 3 (entry / common) | Compressor + dual pressure gauge; inflate each side by hand | ✗ Fully manual | | Level 4 | Adds auto-return to *travel* height only | Travel height, not site levelling | | BCS (premium) | "Horizon" auto-levelling + app; some auto features still "future" | ✓ Roll only, automatically | So the affordable, most-fitted kit is **manual**: you watch a gauge and trim each side yourself. Genuine push-a-button levelling is a premium upgrade — and even then it only levels roll, and the nose is still the jockey wheel. > ✅ **Reality check:** if your van has airbags and you level it by watching a gauge and feeling when it "looks right," you don't have auto-levelling. You have a manual air system doing one axis — and your eye is the sensor. ## The nose is always the jockey wheel This is the bit that surprises people. No airbag system — not even the premium ones — levels the van front to back. Pitch is set at the coupling with the jockey wheel, wind-up or hydraulic. Airbags and jockey wheel solve two different axes, and you always need both. That's also why "airbags replace ramps" is only half true. They reduce how often you reach for a ramp on gentle roll, but they never touch pitch, and a real side slope still exceeds their travel. ## The genuine exception To be fair: true one-button caravan levelling *does* exist. Electric jack systems like Redfoot AutoLift drop four legs and level the van on both axes in under a minute — no ramps, no jockey winding. That's real automation, and worth it for heavy vans or owners who can't manage the manual routine. But it's a premium, four-figure system that adds around 60 kg to your payload — a very different thing from a set of airbags, and not what most people mean when they say their van "levels itself." ## Where airbags genuinely earn their place None of this is a knock on airbags. Bought for the right reason, they're excellent: - **Ride and load-levelling** on long or off-road tows — the real reason to fit them. - **Quick roll trim** on mild slopes without walking around with ramps. - **Adjustable clearance** for rough tracks and steep driveways. Just buy them for the tow, and treat easy side-levelling as the bonus it is — not as the reason. ## What to do instead — or as well Whether you've got airbags or not, you still need to know when the van is level, on both axes. That's exactly what a phone does. OzLevel reads your van's roll and pitch to better than half a degree — six times finer than the ~3° your three-way fridge needs — and tells you the exact ramp height for the low wheel and which way to wind the jockey. It even remembers your hitch height for easy re-hitching. No hardware, no gauge-watching, $9.99 once. > **Try it free.** Open OzLevel at [van.app.ozlevel.com.au](https://van.app.ozlevel.com.au) and level your van — airbags or not — with a precise reading on both axes. It's the cheap, honest first step before spending thousands on suspension you're mostly buying to level a van. ## The verdict Do airbags level your caravan? They help with half the job, within limits, and on most kits you're the one doing it. They're a fine ride upgrade and a handy roll trim — but they're not the hands-off caravan auto-leveller they're often sold as, and they'll never level the nose. Buy them for the tow. Level the van with a precise reading and the two tools you already have: a ramp and the jockey wheel. **Get OzLevel Pro — $9.99 AUD once:** https://ozlevel.com.au/get-pro.html **Try free first:** https://van.app.ozlevel.com.au --- ## Frequently asked questions **Do airbags level a caravan?** Partly. Airbag suspension can raise or lower each side of the van to correct side-to-side roll, within a few inches of travel. It does nothing for the nose (front-to-back pitch), which is always set with the jockey wheel, and a large side slope still needs a ramp. So airbags assist levelling on one axis rather than levelling the whole van. **Is airbag suspension automatic?** Usually not. Entry and mid-tier airbag kits are manual — you watch a pressure gauge and inflate or deflate each side by eye. For example, Cruisemaster's Level 3 kit has no auto-levelling at all, and Level 4 only auto-returns to travel height. Automatic on-site levelling is reserved for premium tiers such as Cruisemaster's BCS, and even then it only levels roll. **Can airbags replace levelling ramps?** Only for small side-to-side corrections within the airbag's travel. On a noticeable slope the correction exceeds what the bags can lift, so you still need a ramp under the low wheel. Airbags reduce how often you reach for ramps; they don't remove the need for them. **Do I still need a jockey wheel and a level with airbags?** Yes. The jockey wheel sets the nose up or down (pitch) on every caravan, airbags or not. And unless you have a premium auto-levelling tier, you still need a way to know when you're level — a spirit level, a wireless indicator, or a phone app like OzLevel that reads both axes to better than half a degree.
