Womala Shock Absorbing Air Pump LR078650 for Land Rover Discovery 4

Product Overview

The Air Suspension Compressor LR078650 is an OE-grade air supply unit engineered for select for Land Rover vehicles with electronic air suspension. This AMK-type unit pressurises the system to maintain proper ride height, adjust suspension stiffness, and ensure comfort and handling balance.

LR078650 is the current replacement part, superseding a chain of earlier numbers including LR072539, LR061888, LR045444, LR044016, and LR044034.

⚠️ Important: This is a non-Hitachi (AMK-style) compressor. Always verify whether your vehicle is fitted with an AMK or Hitachi compressor before ordering — the two are not interchangeable without additional parts.

Key Features

• AMK-type compressor – OES replacement for the factory AMK unit

• Direct replacement fit – utilises the original bracket, pipes, and wiring

• Integrated air dryer – maintenance-free, protects the system from moisture

• Thermal overload protection – prevents overheating under extended operation

• Relay must be renewed – a new relay must be fitted when replacing the compressor

OE Cross-Reference

Technical Specifications

Vehicle Fitment

⚠️ Important: This compressor is for non-Hitachi (AMK) systems fitted from the VIN ranges above. For vehicles with Hitachi compressors, a conversion kit (LR072537) is required.

Signs of Failure

• Vehicle sagging – one or more corners sit lower due to insufficient air pressure

• Noisy or overworking compressor – runs constantly, loud humming or grinding noises, or fails to shut off

• Complete suspension failure – compressor does not activate, leading to loss of ride height adjustment

💡 The main cause of compressor failure is air leaks elsewhere in the system — inspect air springs and lines for leaks before replacing the compressor.

Critical – Verify Your VIN Before Ordering

Air suspension compressors are VIN- and system-type-specific (AMK vs. Hitachi). Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. The relay must be renewed when replacing the compressor — failure to do so may void the warranty. After installation, the suspension system may require calibration using diagnostic equipment.
