Arnott P-3280 Air Suspension Compressor

Arnott P-3280 Air Suspension Compressor

The Arnott P-3280 is a new heavy-duty aftermarket air suspension compressor for select Land Rover full-size SUV applications. It is built as a direct replacement for the original equipment compressor and uses an epoxy-coated finish to help resist corrosion in demanding underbody conditions.

Compatible with 2014-2021 Land Rover Range Rover and 2014-2017 Land Rover Range Rover Sport applications, this compressor assembly includes the dryer, relay, plugs, and brackets needed for an OE-style fit. The Arnott NEW product line focuses on replacement suspension components that match factory-style integration for Land Rover air suspension systems.

What It Helps Address

• Slow or weak air suspension pressure buildup
• Compressor noise from a worn or failing unit
• Suspension height faults caused by inadequate air supply
• Corrosion-related compressor housing deterioration
• Air suspension system performance loss on Range Rover and Range Rover Sport models

Installation Notes

Verify the vehicle’s original compressor configuration before installation and confirm connector, bracket, and mounting-hole alignment. Because this is a direct replacement compressor assembly for Land Rover air suspension systems, proper system diagnosis should be completed before replacing related components such as the valve block or air springs.
