What an Air Lift air suspension kit does

An Air Lift air suspension kit replaces your vehicle's factory coil springs or leaf springs with an air spring system — essentially an airbag that holds up your vehicle instead of metal springs. The kit includes air springs, an air compressor, an electronic control module, and tubing that connects everything together. You control the ride height and stiffness from inside the cab using a switch or smartphone app, depending on which Air Lift model you buy.

The main reason people install these kits is load leveling. When you tow a trailer or carry heavy cargo, the rear of your truck sags. An air suspension kit automatically raises the back end to keep your vehicle level, which improves handling, reduces wear on your suspension, and keeps your headlights pointed at the road instead of the sky. Some drivers also use them for lowering the vehicle at highway speeds to reduce wind resistance and fuel consumption.

Air Lift is the largest manufacturer of aftermarket air suspension systems in North America. They make kits for trucks, SUVs, and vans, and they've been in business since 1958. Their products are sold through truck shops, online retailers, and some dealerships.

Key Takeaways

  • Air Lift kits replace coil or leaf springs with air springs that you adjust electronically, letting you raise or lower your vehicle and level the load.
  • Installation typically costs between $1,500 and $3,500 in labor, depending on your vehicle and whether you need additional modifications.
  • Air springs last 80,000 to 150,000 miles on average, after which they may leak or fail and require replacement.
  • The compressor runs continuously when you adjust height, which can draw extra power from your electrical system and increase fuel consumption slightly.
  • Air Lift offers different product lines — LoadLevel, RideControl, and AirStrike — each designed for different towing and hauling needs.

Air Lift product lines and what each one does

Air Lift makes three main product lines, each with a different purpose and price point. LoadLevel is the entry-level option and is designed purely for load leveling — it raises the rear of your truck when you add weight. It does not lower the vehicle and does not adjust the front suspension. LoadLevel kits are the least expensive and are popular with people who tow occasionally or haul cargo a few times a year.

RideControl adjusts both front and rear suspension and lets you raise or lower the entire vehicle. It includes a compressor, air springs for all four corners, and an electronic control system. RideControl is more expensive than LoadLevel but gives you more control over ride height and can improve handling on uneven terrain. Many truck owners use RideControl to lower their vehicle for better aerodynamics on the highway, then raise it for off-road driving.

AirStrike is Air Lift's premium line and includes wireless smartphone control, faster response times, and more precise height adjustment. AirStrike systems cost significantly more than RideControl but appeal to owners who want the most advanced features and the ability to adjust suspension from outside the vehicle.

Installation, labor costs, and what's involved

Installation requires removing your factory suspension components, installing new air springs and brackets, running air lines and electrical wiring, and programming the control module to your vehicle's specifications. The job typically takes 8 to 16 hours depending on your vehicle's design and whether the shop needs to fabricate custom brackets.

Labor costs vary widely by region and shop. A truck shop in a major city may charge $100 to $150 per hour, while a rural shop might charge $60 to $80 per hour. For a LoadLevel kit on a common truck like a Ford F-150, expect labor to run $1,200 to $1,800. A full RideControl installation on the same truck could run $2,000 to $3,500. Some shops include the kit price in a flat rate; others charge separately for parts and labor.

Before you book installation, confirm that the shop has experience with Air Lift systems on your specific vehicle. Some vehicles require additional modifications — for example, relocating the spare tire, adjusting brake lines, or modifying the frame. These add-ons can increase labor costs by $300 to $800.

How long air springs last and when they fail

Air springs are rubber and plastic components that flex thousands of times per mile. Over time, the rubber degrades and can develop small leaks. Most air springs last between 80,000 and 150,000 miles, though some fail earlier if the vehicle is driven on rough roads or if the compressor is faulty and overworks the springs.

Signs of air spring failure include the vehicle sagging on one corner, the compressor running constantly, a hissing sound from under the vehicle, or the control module displaying an error code. If one air spring fails, you can replace just that one, but many shops recommend replacing all four at the same time to keep the suspension balanced. A replacement air spring costs $150 to $300 per corner, plus $300 to $600 in labor to swap it out.

The compressor itself typically lasts the life of the vehicle if it's not defective from the factory. If it fails, replacement costs $400 to $800 plus installation. Air lines and fittings are less likely to fail but can develop leaks if they're damaged or if the connections loosen over time.

Electrical draw and fuel economy impact

The compressor in an Air Lift system draws power from your vehicle's alternator and battery. Every time you adjust the suspension height, the compressor runs to pump air into or out of the springs. On a truck that's towing or hauling regularly, the compressor might run for several minutes per day, which adds a small but measurable load to your electrical system.

In real-world use, this electrical draw is usually not a problem on modern vehicles with robust alternators. However, if your truck already has a weak battery or an undersized alternator, adding an air suspension system could strain it. Some shops recommend upgrading to a higher-output alternator if you plan to use the system frequently.

Fuel economy impact depends on how you use the system. If you lower your vehicle at highway speeds to reduce wind resistance, you may see a 1 to 3 percent improvement in fuel economy. If you're constantly raising and lowering the suspension, the compressor's electrical draw could offset any aerodynamic gains. Most owners report no noticeable change in fuel consumption.

Maintenance and troubleshooting common problems

Air Lift systems require minimal maintenance compared to factory suspensions. Check the air lines and fittings every 12 months for cracks or loose connections. Listen for hissing sounds, which indicate a leak. Keep the compressor intake filter clean — a clogged filter forces the compressor to work harder and can shorten its life.

The most common problem is a slow leak in one of the air springs. If your truck sags overnight or over a few days, the system likely has a leak. You can locate it by spraying soapy water on the air springs and fittings while the compressor is running — bubbles will form at the leak. Small leaks in the rubber can sometimes be sealed with a patch kit, but most shops recommend replacing the entire air spring.

If the compressor runs constantly and the vehicle won't hold height, the problem is usually a failed air spring or a leak in the air lines. If the control module won't turn on or displays an error code, the issue is likely a blown fuse, a loose electrical connector, or a faulty module. Most of these problems can be diagnosed with a basic scan tool, and many truck shops can handle the repair.

Comparing Air Lift to other air suspension brands

Air Lift is not the only manufacturer of aftermarket air suspension kits. Other brands include Firestone, Arnott, and Ridetech, each with different price points and feature sets. Firestone air springs are often less expensive than Air Lift and are compatible with some Air Lift compressors, making them a budget-friendly replacement option. Arnott specializes in air suspension for luxury vehicles and SUVs. Ridetech focuses on performance and lowriding applications.

Air Lift's advantage is availability and parts support. Because they're the market leader, most truck shops stock Air Lift components and have technicians trained on their systems. Replacement parts are widely available online and at truck shops. If you choose a less common brand, you may have trouble finding replacement air springs or getting service at a local shop.

When comparing kits, look at warranty coverage. Air Lift typically offers a one-year warranty on the compressor and a two-year warranty on air springs, though this varies by product line and retailer. Some competitors offer longer warranties, but warranty claims often require shipping the component to the manufacturer, which can take weeks.

Frequently Asked Questions

Can I install an Air Lift kit myself if I have basic mechanical skills?

Installation requires removing suspension components, running air lines under the vehicle, and programming the control module. Unless you have experience with suspension work and access to a lift, this is not a DIY job. Most manufacturers recommend professional installation to may support safety and warranty coverage.

Will an air suspension kit void my vehicle's warranty?

It depends on your vehicle's manufacturer and what components you modify. Some manufacturers void the entire warranty; others only void the suspension warranty. Check your owner's manual or contact your dealership before installation. Many aftermarket shops carry their own warranty on the kit and installation labor.

How do I know if an Air Lift kit is compatible with my vehicle?

Air Lift publishes a compatibility chart on their website and in their product catalogs. You'll need your vehicle's year, make, model, and engine size. Most common trucks and SUVs have kits available, but some newer models or specialty vehicles may not. Contact Air Lift or a truck shop directly if you're unsure.

What happens if the compressor fails while I'm towing?

If the compressor fails, the air springs will gradually lose pressure and your vehicle will sag. You can still drive, but the ride will be rough and the vehicle may sit lower than normal. You should not tow a heavy load with a failed compressor because the suspension won't support the weight properly. Have the compressor repaired or replaced before towing again.

Can I use an air suspension kit with a fifth-wheel or gooseneck trailer?

Yes. Air suspension kits are designed for heavy towing and work well with fifth-wheel and gooseneck trailers. In fact, these heavier trailer types are one of the main reasons people install air suspension — the kit automatically levels the truck bed and keeps the hitch at the correct height. Make sure the kit you choose is rated for your trailer's weight.
