Air suspension systems have travel a agelong measurement successful caller years, infiltrating nan mainstream automotive marketplace aft being a niche action connected ultra-luxury vehicles. As nan sanction suggests, aerial suspension setups do distant pinch nan accepted metallic springs that are a portion of astir modular suspension systems and switch them pinch dense work rubber aerial bags. These aerial bags are connected to an aerial compressor and are monitored by sensors that find really overmuch unit is basal to support a fixed load weight aliases a desired driving profile.
Air suspension systems, depending connected their intended purpose, supply adjustability that tin automatically level-out heavy loaded vehicles, supply a cushy soft aliases patient and sporty thrust value astatine nan touch of a button, aliases raise and little nan thrust height. Expensive luxury cars often usage aerial suspension to supply a soft thrust and isolate nan assemblage of nan conveyance from nan undulations of nan roadworthy surface. Off-road vehicles often usage aerial suspension to support nan conveyance astatine a much reasonable thrust tallness erstwhile operating connected paved surfaces, but tin inflate to assistance nan conveyance and connection much crushed clearance for all-terrain driving. Pickup trucks and different dense instrumentality besides usage aerial suspension systems to support nan conveyance level sloppy of nan load complete 1 axle. These systems are invaluable to galore drivers, but arsenic pinch everything, location are pros and cons.
Benefits of aerial suspension systems

Air suspension systems are very versatile. They tin make a car thrust for illustration it's driving connected a cloud, but they tin besides patient up to support nan very aforesaid car level arsenic it performs high-speed handling maneuvers. These systems are known for their expertise to supply a beautifully isolated thrust value since nan conveyance is really riding connected a cushion of air. Luxury cars are often fitted pinch aliases astatine slightest offered pinch aerial suspension systems for this reason. Some luxury cars person aerial suspension systems that are informed by a camera that sounds nan roadworthy ahead, truthful nan aerial bags tin slacken to soft retired harsh bumps aliases patient up successful anticipation of a area aliases unsmooth surface.
High-end off-road vehicles often usage aerial suspension systems to supply that aforesaid buttery soft thrust value successful astir situations, but their aerial suspension systems are designed to run arsenic assistance systems, too. When nan driver selects an off-road driving mode aliases erstwhile they prime a raised suspension position, nan aerial compressor inflates nan aerial bags to higher levels to assistance nan conveyance higher disconnected nan ground, frankincense expanding crushed clearance, arsenic good arsenic improving nan vehicle's approach, breakover, and departure angles. These systems tin often little nan vehicle, too, which improves on-road handling arsenic good arsenic aerodynamic efficiency.
Pickup trucks and ample SUVs often usage aerial suspension systems to support vehicles level, sloppy of really heavy nan conveyance is loaded up. Even purpose-built dense work trucks tin sag astatine nan rear if nan furniture is loaded up adjacent to nan vehicle's maximum payload aliases towing capacity, but aerial suspension tin patient up to mitigate that sag. The aforesaid goes for ample SUVs which whitethorn acquisition suspension squat erstwhile afloat loaded pinch passengers aliases luggage.
Air suspension drawbacks
The superior drawbacks of astir aerial suspension systems are their first price, their costs to maintain, and nan superior issues they origin erstwhile they do fail. Air suspension requires a blase array of technologies that request to activity successful tandem successful bid to run properly. Each instrumentality needs its ain aerial bag, each aerial container needs its ain tallness and load sensors, each aerial container needs to person lines that link it to nan aerial tank, and that vessel needs a compressor to compress nan aerial needed to capable each bag. This analyzable array of exertion has galore imaginable nonaccomplishment points, and pinch thing that bears respective thousands of pounds of weight and vibrational maltreatment each clip a conveyance is driven, aerial suspension systems deterioration retired and neglect spectacularly.
If you've ever seen an aged Range Rover, Tesla Model S, aliases Mercedes-Benz R-Class that sits conscionable a fewer inches disconnected nan roadworthy and appears to beryllium violently pogoing disconnected of each small pavement imperfection, past you've seen a conveyance pinch a surgery aerial suspension. The aerial bags that dress up an aerial suspension are made of a dense work people of rubber, but complete nan people of respective years, they tin create cracks aliases leaks that origin nan conveyance to suffer each of its suspension. Some cars had aerial suspension connected nan rear wheels only, truthful you tin spot aged Lincoln Town Cars pinch grounded aerial suspension exhibiting a nasty squatted rear end. Naturally, repairing and replacing these analyzable systems tin beryllium an costly and labor-intensive process.
Even erstwhile new, galore cars connection aerial suspension arsenic a costly add-on option. Take nan 2025 Mercedes-Benz E350 for example; it offers nan brand's AirMatic package arsenic a $3,200 option. The package besides includes rear-axle steering, but overmuch of that further costs goes toward paying for nan analyzable aerial suspension system.
Aftermarket aerial suspension is simply a communal inclination among customizers
Beyond OEM aerial suspension systems, galore car customizers admit nan versatility offered by "bagging" a car. "Bagging" a car is simply a word utilized to picture vehicles that are fitted pinch aftermarket aerial suspension systems that often let nan car to thrust astatine a reasonable thrust tallness connected nan road, but erstwhile parked they tin deflate and beryllium impossibly low. This benignant of aftermarket customization tends to beryllium strictly aesthetic, but it's really much applicable than a car that's lowered connected fixed springs since aerial springs tin beryllium raised to let a conveyance to traverse velocity bumps, dips, and different roadworthy conditions without calamity.
Aftermarket aerial suspension kits are besides offered arsenic "helper springs" for folks who often tow aliases haul dense loads. These kits supplement a vehicle's modular suspension system, and don't usually switch components. They simply remainder unused erstwhile nan conveyance is unloaded, but erstwhile nan conveyance is loaded up aliases erstwhile a trailer is hooked up, nan proprietor tin inflate nan aerial springs to forestall undesirable driving characteristics caused by hauling a dense load. They do not summation a vehicle's maximum towing aliases payload capacity, but they do thief support nan conveyance level and safe erstwhile carrying loads adjacent its weight limit.
If you worth nan comfortableness of your luxury car complete each else, aliases if you worth nan duality of a demure on-road driving acquisition paired pinch nan maximum crushed clearance for off-road abilities connected your luxury SUV, past aerial suspension mightiness beryllium correct for you. Most drivers, though, will beryllium conscionable good pinch bully aged fashioned shocks, springs, and struts.
