Arnott D-2171 Air Suspension Compressor Dryer

Arnott D-2171 Air Dryer for Air Suspension Systems

The Arnott D-2171 is a standard air suspension compressor dryer built for vehicles that rely on clean, dry compressed air to maintain ride height and suspension performance. It is an air dryer with a 2-hole design and a rubber/Fabris-CR/PA housing construction for use in compatible Ford, Lincoln, and Mercury applications.

Key Features

• Air suspension compressor dryer for moisture control in the air system
• 2-hole air dryer design with 2 ports
• Standard grade type
• Housing material: rubber/Fabris-CR/PA
• Mounting hole quantity: 1
• Fittings not included
• Mounting hardware not included

Detailed Description

Arnott D-2171, part number D-2171, is used in air suspension systems to help manage moisture in compressed air before it reaches suspension components. By keeping the air supply drier, the compressor dryer supports consistent operation in vehicles such as the Ford Crown Victoria, Lincoln Town Car, Mercury Grand Marquis, and Lincoln Continental across the listed model years. This air suspension compressor dryer is a direct-fit service component for compatible applications that use a 2-hole dryer layout and a single mounting hole.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Moisture buildup in the air suspension compressor circuit
• Reduced air system efficiency caused by saturated dryer media
• Air suspension performance issues related to contaminated compressed air
• Premature wear in compressor and valve components from excess moisture
• Ride-height inconsistency in air-suspension-equipped vehicles

Installation Notes and Tips

Verify the vehicle’s air dryer layout before installation. This Arnott D-2171 uses 2 ports and a single mounting hole, and it does not include fittings or mounting hardware. Confirm the existing compressor dryer configuration on the Ford Crown Victoria, Lincoln Town Car, Mercury Grand Marquis, or Lincoln Continental to ensure the replacement matches the original setup.

Quality Assurance

Arnott supplies suspension components for air-ride applications, and this dryer is built as a standard replacement part for the listed fitments. Part number D-2171 is intended for vehicles that require a 2-hole air suspension compressor dryer in the specified model years.
