Arnott P-3431 Air Suspension Compressor

The Arnott P-3431 is a NEW air suspension compressor assembly for select Land Rover air ride systems. Built to OE specifications, it replaces the problematic Hitachi compressor used on Range Rover Sport, LR3, and LR4 applications with a direct-fit 12V unit.

Arnott’s NEW product line focuses on OE-style replacement components for air suspension repairs, and this compressor follows that approach with a pre-wired design for fast plug-and-play installation. The assembly includes an integrated dryer, relay, thermal overload protection, hoses, fasteners, a bracket, and a protective cover for a complete compressor replacement package.

What It Helps Fix

  • Compressor failure that prevents the air suspension from building pressure
  • Slow or inconsistent ride-height changes
  • Air suspension warning messages related to compressor performance
  • Excessive compressor run time caused by a worn dryer or relay
  • Loss of OE-level air supply on Range Rover Sport, LR3, and LR4 models

Installation Notes

The compressor arrives pre-wired for straightforward installation and includes the bracket and cover needed to replace the OE pump and cover. If you are replacing the original Hitachi compressor, a dealer-provided software update is required after installation. Verify vehicle fitment by year, model, and VIN before ordering, especially for 2012 LR4 applications up to VIN 639077.

Quality Assurance

Arnott builds this compressor to OE specifications for direct replacement use in Land Rover air suspension systems. The unit includes an integrated dryer, relay, thermal overload protection, hoses, and fasteners to support a complete compressor service.
