On air suspension systems, some items may have to be replaced or serviced over time depending on how much you use your system and what type of climate you are in. Our eLevel+ kit utilizes ride height sensors to read where your vehicle currently sits to give you accurate readings in your e+ app. These AccuAir e-Level sensors feature a plug and play design to make them fully replaceable if you have one become damaged or start to malfunction. This sensor is a direct replacement for the sensors found in all e-level kits and will help get your air suspension system functioning properly again. This is a sensor only, the linkage and hardware are not included.
