Buying new air suspension vs used air suspension
If you've been hunting Marketplace or the forums and stumbled across a deal on a used air suspension kit, we get it... the price is tempting. But before you pull the trigger, there are a few things worth understanding about what you're actually buying. Used air ride can work out. It can also go sideways fast. Here's how to think through it.

Is buying used air suspension worth it?
Honestly, it depends. The single biggest factor is how the previous owner treated the kit, and that's also the thing you have almost no way of knowing just from looking at photos online. A well-maintained kit from someone who knew what they were doing can be a legitimate deal. A kit from someone who didn't know what they were doing can cost you more in repairs than you saved on the purchase.
Air suspension is a wear item, just like brakes, tires, or bushings. When you buy used, those parts are already somewhere in their life cycle. You just don't know where. That uncertainty is the core of the used air ride gamble, and it's worth taking seriously before you commit.
The money saved upfront is real. But so is the risk. The question is whether the delta between the used price and a new kit is worth taking on unknown history, unknown condition, and zero warranty coverage.
What to check before buying used
If you're committed to going the used route, go in with a checklist. These are the things worth asking about and inspecting before money changes hands.
Check 01
Upper mount bushings and bearings
Depending on the kit, this will be a nylon bushing or a pillow ball spherical bearing. Both wear out over time. Budget to replace these before installation regardless of how the kit looks, around $60 per corner for sphericals. If you skip this and install a sloppy bearing, you're pulling the whole kit back out to fix it.
Check 02
Strut length and adjustment
Ask the seller if they adjusted the overall strut length and by how much. Most kits ship pre-threaded to the correct length for the vehicle. If the previous owner shortened it significantly thinking it would help them go lower, they may have caused topping-out damage, which you won't see until a damper fails.
Check 03
Damper condition
Look for any oil weeping from the damper body, that's a sign the seals are going. Bounce the corners and feel for any unusual resistance or clunking. A damper that's been topped out repeatedly will feel different than a healthy one, though it takes some experience to know what you're feeling for.
Check 04
Bag condition
Inspect the air bags for cracking, dry rot, or any visible wear on the rubber. A bag that's been cycled thousands of times will show it. Check that all the fittings and ports are undamaged. A cracked bag isn't the end of the world — but it's a replacement cost to factor into what you're actually paying for the kit.
Check 05
Compressor hours and condition
Compressors have a finite duty cycle and wear out with use. Ask how long the system has been running and how frequently the car was driven. A compressor on a daily driver for three years has seen significantly more use than one on a weekend show car. Listen for any unusual noise when it runs.
Check 06
Management system
Test the controller if at all possible before purchasing. Make sure all valves open and close correctly, presets save properly, and the display functions as expected. Management systems can fail in ways that aren't visually obvious, a unit that looks fine might have a valve that doesn't fully close, causing a slow leak.
The hidden risks of used air ride
Beyond the obvious wear items, there are a few less obvious risks that catch people off guard when buying used.
Risk 01
Topping-out damage you can't see
Inside a monotube damper there's a plastic bump stop that protects against metal-on-metal contact when the suspension is fully extended. If the previous owner drove around regularly in a topped-out condition, often from shortening the strut too much, that bump stop gets flattened. Once it's gone, you get metal-on-metal impact and eventually a blown damper. You won't see this coming until it's too late.
Risk 02
Outdated tech
Air suspension design has improved significantly over the years. Older kits use pillow ball spherical bearings in the upper mount - newer designs have moved to radial bearings that last significantly longer. Just because a kit fits your vehicle doesn't mean it's the most current version. You might be buying a design that's already been superseded by something better.
Risk 03
No warranty
When you buy new from Bag Riders, you have a warranty and a support team that knows your kit. If something goes wrong, you have a path forward. With used, you're your own warranty. Every failure comes out of your pocket. Budget accordingly.
Risk 04
Incomplete kits
Used kits often come missing pieces - a valve, a fitting, a bracket, hardware that got lost during a removal. What looks like a complete kit in photos may need $100–$300 in replacement parts to actually be complete and functional. Factor that into what you're really paying.
New vs used - side by side
Here's the honest comparison. Neither option is universally right, but one of them comes with a lot more unknowns.
Buying new
- Current production version with the latest tech
- Full lifespan ahead of you - zero unknown history
- Warranty coverage and real support if something fails
- Everything included, matched, and ready to install
- Higher upfront cost
Buying used
- Lower upfront cost
- Unknown history - no way to know how it was treated
- No warranty - every failure is your expense
- May be an older design with outdated components
- Budget extra for wear items and potentially missing parts
Our honest take
We've been selling air suspension since 2009 and we've seen both outcomes. People who got a great deal on a used kit and people who spent more fixing a used kit than they would have spent buying new. The difference almost always comes down to the previous owner.
If you're going to buy used, go in with realistic expectations. Replace the wear items before you install. Budget for the possibility that something will need replacing in the first year. And if the price difference between the used kit and a new one is only a few hundred dollars, seriously consider just buying new. The warranty alone is worth more than that in peace of mind.
If you find a well-documented, low-use kit from someone who clearly knew what they were doing and can demonstrate it was set up correctly, that's a different conversation. Those deals exist. But they're not the norm.
