Range Rover L322 Compressor and Valve Block Package

Compressor and Valve Block Package for the Range Rover L322: compressor, valve block and relay replaced together, because they fail together.

Air suspension fails as a system rather than a part. A leaking air spring makes the compressor run longer, the compressor gets hot and wears, and the valve block ends up working against both. Replacing the part that failed last usually means paying for the next one within a year. These packages replace the parts that wear together, and the conversions are offered honestly: coil springs are cheaper to run, lose the height adjustment and the ride quality, and need declaring to your insurer. The L322 is the Range Rover that most people can now afford to buy and not all can afford to run, which is exactly why honest parts prices matter on it.

Fitting

Labour guide: about 3 hours. Land Rover changes specification mid production, often by VIN rather than by model year, so send the VIN or the registration with the order and we confirm the part against the build data before anything leaves. It takes two minutes and it is the difference between a part that fits and a return. We are an independent Land Rover specialist and parts supplier. We are not Land Rover or Jaguar Land Rover and are not appointed by them; the model names are their trademarks and are used here to describe fitment. Everything we sell is chosen for vehicles that actually get used: towed with, loaded, driven through water and parked in fields, rather than for the brochure.
