Electric Over Hydraulic Adapter Module For a 2024 Chevrolet Silverado 2500HD  

Updated 06/05/2025 | Published 08/18/2023



Question:

Expert Reply:

I have to go off the GM dealership recommendation. If they are saying you need the Hydrastar # HBA-CAM or Dexter # DX35FR adapter module for your factory brake controller to work with your electric over hydraulic brake actuator, then I can't really deny it. The main issue is the factory brake controllers are controlled by the ECU on the truck and as trucks continue to change one year you may not need the adapter and the next you you may. Since they have started doing over the air updates as well one day everything will work fine and the next day the programming could change everything.

@Brian For that actuator you would need the # HBA-CAM. Basically it installs the exact same.

This is exact same adapter as the Dexter part number you mentioned with the part #DX35FR. Now with that said your 2022 Ford F-250 shouldn't need this adapter so that makes me think you just need to put your brake controller into hydraulic mode.
