Is My OEM Brake Controller in My 2020 GMC 2500 HD Diesel Compatible with Electric Over Hydraulic?  

Updated 08/27/2025 | Published 08/12/2025



Question:

I have a 2020 GMC 2500 HD diesel. I am having disc brakes installed on my fifth wheel camper. Moyrride is installing Deemaxx disc brakes. Is there anything available that will allow me to continue using the factory truck trailer breaking system? Thank you for your help Andy.

Hello Andy,

Making the swap over to disc brakes, you will not be disappointed!

I am showing that your OEM brake controller in your 2020 GMC 2500 HD Diesel is compatible with Electric Over Hydraulic brakes that are being installed. I added a picture of the chart.

If you find out for some reason that yours is not compatible for the DeeMaxx Alpha G1600 Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # DE47SR, you could add the Hydrastar Electric Over Hydraulic Actuator Adapter Module for Ford and Chevy Brake Controllers # HBA-CAM.

Have you gone on any fun adventures this summer? Where did you go, or what has been your greatest adventure yet?
