Womala Air Suspension Compressor Assembly LR072537 for Discovery 3/4 LR3/4 Range Rover Sport

Product Details: Air Suspension Compressor Assembly - LR072537

This air suspension compressor assembly is a precision-engineered component designed for vehicles equipped with electronic air suspension. It serves as the central unit that generates and maintains compressed air for the air spring system, enabling automatic ride height adjustment and load leveling.

Core Function: The compressor pressurizes and supplies air to the air suspension struts, allowing the vehicle to automatically adjust ride height based on load, speed, and terrain. It works in conjunction with height sensors and the electronic control unit to maintain a level stance, enhance stability, and provide optimized ground clearance. A failing compressor often results in a sagging vehicle, extended leveling times, or an illuminated suspension warning light.

Technical Specifications:

Failure Symptoms:

• Vehicle sagging on one or more corners

• Extended time to raise or lower the vehicle

• Air suspension warning light illuminated on dashboard

• Frequent compressor cycling (running too often)

• Rough ride quality or unusual noises from compressor area

• Compressor running excessively or not at all

Note: This compressor is designed for vehicles equipped with AMK-type air suspension systems. It is a direct replacement for all non-Hitachi vehicles. When replacing a Hitachi-style compressor with this AMK unit, the full installation kit (including bracket, wiring, and relay) ensures proper fitment. Before installation, inspect the entire air suspension system for leaks, as leaking air springs are the most common cause of compressor failure. Verify compatibility using your vehicle's VIN number and chassis number before purchasing. Professional installation is highly recommended, and a wheel alignment should be performed after any suspension work.

A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.

A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
