Arnott: Video Installation for Land Rover Discovery (LR3-LR4) and Range Rover Sport

In this video we show automotive repair professionals how to remove and install the AMK Air Suspension Compressor from Arnott for the 2005-2014 Land Rover Discovery LR3, LR4, and 2006-2017 Range Rover Sport.

The AMK Air Suspension Compressor part P-2645, is designed to replace the problematic Hitachi OE compressor. This AMK air supply unit includes a bracket so it can easily replace the OE pump and bracket. This new compressor includes a release solenoid and an integrated dryer and filter. The compressor comes pre-wired with new air hoses and fittings for plug and play operation. This AMK compressor comes with vibration isolators, mounting hardware and a new compressor relay. If replacing the OE Hitachi compressor a dealer provided software update is required.
