The H&R ETS electronic module is designed for cars with OEM air suspension systems. The ETS module allows a suspension lowering of up to 40mm from the stock setting, which improves the appearance of the vehicles and reduces the center of gravity for improved handling. 

The original height adjustment switch and functionality are retained. Many H&R ETS modules feature "Plug-and-Play" installation with no wire cutting/splicing required. 

Lowering with H&R ETS enhances the look of your vehicle with a reduced fender well gap, and improves handling with a lower center of gravity. H&R ETS retains the factory height adjustment switch and its functionality. H&R ETS modules come with all the parts required for installation. The ETS unit is easily removed whenever you want to return your car back to factory specification.

The H&R ETS module comes with all necessary mounting components along with detailed installation instructions.
