Unity Rear Air Spring Kit 2-15-573000-H

This rear air spring kit is designed for 2005-2009 Land Rover LR3 and 2010-2016 Land Rover LR4 models. It provides a complete replacement solution for worn or failed rear air suspension components. The kit includes two suspension air spring bags and a fully assembled air compressor unit with preassembled brackets and electrical connectors. It is intended for owners and mechanics restoring the original air ride system on these specific vehicles.

Thermals, noise and power draw

The air compressor operates from the vehicle's electrical system and activates only when the suspension requires pressure adjustment. During normal driving the compressor runs intermittently, drawing current for short periods before shutting off. The air spring bags themselves are passive components that contain pressurised air and generate no heat or noise. Cabin noise remains unchanged because the system operates independently of the engine and drivetrain.

Sustained load behaviour

Under continuous heavy loading or frequent height adjustments the compressor will cycle more often to maintain the target ride height. The unit is built for repeated duty cycles matching the original equipment specifications for these Land Rover models. The air spring bags are constructed to withstand constant pressure variations during extended journeys or when carrying maximum payload. The preassembled brackets and connectors are designed to remain secure through prolonged vibration and thermal cycling.
