Frequently Asked Questions

What is the Arnott Warranty on Air Suspension parts?: Some parts sold to North American customers have a Limited Lifetime Warranty. Others, including compressors, have a Two-Year Warranty. International orders come with a Two-Year Warranty on all Arnott parts. The Arnott Warranty is non-transferable. If a part is defective Arnott will either replace or repair that part, as long as it is within the warranty period and proof of purchase is available. Arnott does not offer a warranty on parts used in commercial vehicles. Improper use or installation is not a manufacturer's defect.
Why do some of your compressors look different from the original factory part?: Some Arnott compressors feature improvements to the original design. For example, the aftermarket compressor for the Lincoln Continental Mark VIII has an internal filter rather than an external filter. Also, sometimes customers confuse the air suspension compressor with the ABS (brakes) compressor. The ABS compressor will have metal lines, rather than plastic.
Which side of my car is the Right and Left?: The right and left sides of an automobile are determined as if sitting in the car facing forward. Thus, the left side is on the left when sitting in the car facing forward, and the right side is on the right. For American cars, the driver’s side is on the left, and the passenger sits to the right of the driver. For cars in Japan, Britain, Ireland, the Bahamas and some other former British colonies -- where they drive on the left side of the road -- the passenger sits on the left side, and the driver (along with all the driving controls) is on the right.
Do Arnott products include instructions?: Some Arnott parts include manuals and some do not. If available, instructions will be shipped along with your part. In addition, all available installation manuals can be downloaded from the Arnott website.
What are Variable-Rate Coil Springs?: Variable-rate coil springs are metal springs designed to change stiffness as they deflect. A variable-rate spring uses coils of varying thickness or spacing to provide a softer ride when the vehicle is carrying a light load, but a firmer ride when the load increases. On many vehicles, the rear air springs can be replaced easily with variable-rate springs. While variable-rate springs can help with heavier loads, they are not meant to be a replacement for load-leveling air suspension in vehicles used to tow large trailers or heavy loads.
Will Arnott aftermarket air suspension parts ride differently from the originals?: No. Arnott aftermarket air springs are just like the originals. You will not notice any difference in ride quality. Arnott designs its air springs with the same spring rate and load capabilities set by the original manufacturer.
Where are Arnott parts made?: Most Arnott parts are assembled at Arnott's Merritt Island, Florida facility using high-quality foreign and domestic components. Foreign materials are part of many of the import cores Arnott remanufactures, OE compressors Arnott sells, and various components used to assemble Arnott springs, new and remanufactured parts, and conversion kits.
Should I replace my air suspension parts or just convert my car to coil springs?: If you like the load-leveling capabilities, or if you tow with your vehicle, then you should repair the air suspension system. If you are tired of replacing the many components of which your air suspension consists, then Arnott's coil spring conversion kit should be perfect for you.
Do I have to weld or modify my car to make Arnott coil spring conversion kits fit?: Absolutely not! Arnott conversion kits are designed to bolt directly to your vehicle's suspension. No special tools are necessary to install Arnott conversion kits. Arnott kits come preassembled and ready to bolt in. All Arnott suspension brackets are specifically engineered for your vehicle, and CNC-machined at the Arnott factory in Merritt Island, FL.
How long do air suspension parts last?: Air springs normally last 80,000 to 100,000 miles. Over this time, the rubber bladder dries out, and cracks appear around the bottom piston. Compressors usually wear out because of leaky air springs. However, the computer and height sensors generally last the life of the vehicle.
How do I remove the air lines from my compressor dryer or solenoid?: The air lines are removed by pushing in on the fitting and pulling out on the line at the same time. The fitting usually has an orange plastic ring around it. If it does not, that is okay ... simply push in on the brass fitting instead.
