Range Rover L405 Adaptive Damper Set

Adaptive Damper Set for the Range Rover L405: four adaptive dampers for the electronically controlled suspension.

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 L405 is aluminium bodied with four corner air suspension and adaptive dampers, and its parts are dearer than the earlier cars for good reasons.

• Four adaptive dampers

Fitting

Labour guide: about 5 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.

Which version to buy

OE Supplier is made by the firm that supplies the factory, in its own box rather than a dealer box. Same part, same line, typically 30 to 40 per cent cheaper than the dealer. Premium Aftermarket is a well regarded aftermarket maker that is not the original supplier. Generally good, and we say where the differences are.
