Arnott makes replacement air suspension parts for vehicles that use air springs instead of traditional coil springs
Arnott is a manufacturer of air suspension components — the parts that replace or repair air spring systems in vehicles. If your car, truck, or SUV has air suspension (sometimes called an air spring system), Arnott produces the replacement springs, struts, compressors, and related hardware that shops install when those parts fail or wear out.
Air suspension systems use pressurized air chambers instead of metal coils to support your vehicle's weight and absorb bumps. When these air springs leak, rupture, or the compressor stops working, the suspension sags, the ride becomes rough, or warning lights appear on your dashboard. Arnott parts are what repair shops order to fix these problems.
You do not order Arnott parts directly as a consumer. A mechanic or suspension shop orders them for you when they diagnose an air suspension failure. Understanding what Arnott makes and what it costs helps you know what to expect when a shop quotes you a repair.
Key Takeaways
- Arnott manufactures air springs, struts, compressors, and valve blocks — the core components of air suspension systems in luxury and performance vehicles.
- Air suspension failures show up as sagging ride height, rough handling, warning lights on the dashboard, or a hissing sound when the vehicle is parked.
- Repair shops source Arnott parts through distributors; you order through your mechanic, not directly from the manufacturer.
- Arnott parts typically cost less than original equipment manufacturer (OEM) parts from the vehicle's brand, but more than aftermarket alternatives from other suppliers.
- Installation labor is usually the larger cost than the part itself, because air suspension work requires specialized tools and knowledge.
What Arnott air suspension parts include
Arnott produces four main categories of air suspension components. Air springs (also called air struts or air bellows) are the pressurized chambers that hold up your vehicle. Strut assemblies combine the air spring with the shock absorber in one unit. Compressors pump air into the system and maintain pressure. Valve blocks and manifolds control where air flows and regulate pressure to different wheels.
The company also makes smaller parts like air lines, fittings, and electronic control modules that manage the system. Most shops order complete strut assemblies from Arnott rather than individual springs, because a complete unit is faster to install and comes with all the seals and hardware needed.
Arnott parts are designed to fit specific vehicle models — a Mercedes air spring is different from a BMW air spring, which is different from a Range Rover air spring. When you get a quote, the shop will specify which vehicle year, make, and model the part is for.
Which vehicles use air suspension systems
Air suspension is standard on luxury and high-end performance vehicles. Mercedes-Benz, BMW, Audi, Porsche, and Range Rover use air suspension on many models. Some Cadillac, Lincoln, and Lexus models also have air suspension. Certain trucks and commercial vehicles use air suspension for load-leveling.
Most economy and mid-range vehicles use traditional coil spring suspension, so Arnott parts do not explore to them. If you own a Honda Civic, Toyota Camry, or Ford F-150 with standard suspension, you will not need Arnott parts.
If you are unsure whether your vehicle has air suspension, check your owner's manual or ask your mechanic. Air suspension vehicles often have a button or menu option on the dashboard labeled "Suspension," "Air Suspension," or "Adaptive Suspension."
When air suspension fails and what it costs
Air suspension components fail over time due to wear, age, and exposure to road salt and moisture. Air springs typically last 80,000 to 100,000 miles, though some fail earlier. Compressors can last the life of the vehicle or fail unexpectedly. When a component fails, you will notice the vehicle sitting lower on one or more corners, a rough or bouncy ride, or a warning message on the dashboard.
A single Arnott air spring or strut assembly typically costs between $300 and $800, depending on the vehicle. A compressor runs $400 to $1,200. Installation labor is usually $200 to $600 per component, and many shops recommend replacing springs or struts in pairs (both sides of the vehicle) to maintain even handling. Total repair cost for a complete air suspension overhaul can reach $2,000 to $4,000.
OEM parts from the vehicle manufacturer cost more — sometimes 50 to 100 percent more than Arnott. Other aftermarket suppliers may cost less than Arnott but may not carry the same warranty or quality reputation. Your shop can explain the price difference and what warranty comes with each option.
How to know if you need an Arnott part
You do not diagnose this yourself. If your vehicle has air suspension and you notice sagging, a rough ride, or a suspension warning light, take it to a shop that works on air suspension systems. The mechanic will connect a diagnostic scanner to read fault codes, inspect the air springs and compressor visually, and sometimes perform a pressure test to pinpoint the failure.
Common signs of air suspension failure include: the vehicle sits noticeably lower on one side, the ride feels bouncy or unstable, you hear a hissing sound when parked (air leaking), or a warning light labeled "Suspension," "Air Suspension," or "Service Suspension" appears on the dashboard.
Once the shop diagnoses the problem, they will tell you which component failed and quote you a price for repair. At that point, you can ask whether they use Arnott parts, what the warranty is, and whether OEM or other aftermarket options are available. Some shops specialize in air suspension and stock Arnott parts; others order them as needed.
Arnott warranty and quality reputation
Arnott parts typically come with a manufacturer's warranty that ranges from one to three years, depending on the specific component and the shop's warranty policy. The warranty usually covers defects in materials or workmanship, not damage from accidents or improper installation.
Arnott has been in business since 1997 and is one of the larger aftermarket air suspension suppliers. Many independent shops and some dealerships use Arnott parts as their standard replacement option. The company is known for producing parts that fit correctly and last, though like any aftermarket component, they are not identical to original factory parts.
If a part fails under warranty, the shop handles the warranty claim with Arnott, not you. Keep your receipt and warranty paperwork in case you need to reference it later.
Frequently Asked Questions
Can I drive my vehicle if the air suspension is broken?
You can drive it short distances, but not safely for long. A failed air spring causes uneven ride height, poor handling, and reduced braking stability. Many vehicles with failed air suspension will not pass a safety inspection. Have it repaired before driving it regularly.
Do I have to use Arnott parts, or can I use a different brand?
You can use other aftermarket brands or OEM parts. Arnott is one option among several. Your shop can explain the differences in price, warranty, and fit. Some shops prefer Arnott because of availability and reputation; others use different suppliers.
How long does air suspension repair take?
A single strut or spring replacement usually takes two to four hours. A full system overhaul with compressor and multiple springs can take a full day or longer. The shop can give you a timeline once they know what needs to be replaced.
Will repairing air suspension with Arnott parts affect my vehicle's warranty?
If your vehicle is still under the manufacturer's warranty, check your warranty paperwork or ask the dealership before using aftermarket parts. Some dealerships will service air suspension at no cost under warranty; others may void warranty coverage if you use non-OEM parts. Independent shops are not bound by manufacturer warranty rules.
Is air suspension worth repairing, or should I replace it with regular springs?
That depends on your vehicle and how long you plan to keep it. Repairing with Arnott parts is usually cheaper than converting to coil springs, which requires extensive modification. If your vehicle is near the end of its useful life, conversion might make sense. Discuss this with your mechanic.
